Is composer available as a set of PHP scripts? - php

I haven't found any way of installing composer on my shared hosting. I don't understand the insistence of using a phar, surely composer could comfortably be ported to plain PHP scripts? Is there such a port? Or a way of achieving the same?

A phar file is a PHP archive. So download the composer file locally and upload them to your server. You need only a PHP-Interpreter installed on your CLI.
Then you can run them php composer.phar or without PHP if your host is correctly configured.
http://php.net/manual/de/phar.using.intro.php
https://getcomposer.org/download/
Normally you can install composer with the given command on the composer site.
php -r "readfile('https://getcomposer.org/installer');" | php

cs-cart add on giving error cscart-sdk is not recognized

I have developed a cs cart add on, But when I make a zip of it and try to upload it from gui it gives wrong structure data
so after little research I got that, I have to follow some steps of given in following url.
https://github.com/cscart/sdk
But after successful installation of composer, When I run the command
cscart-sdk command:name
It gives me error
cscart-sdk is not recognized as an internal or external command
I am very new to cscart add-on development
There seems to be something wrong with your composer install, please follow this tutorial (this is where cscart also relates to)
Installation - Linux / Unix / OSX#
Downloading the Composer Executable#
Composer offers a convenient installer that you can execute directly from the commandline. Feel free to download this file or review it on GitHub if you wish to know more about the inner workings of the installer. The source is plain PHP.
There are in short, two ways to install Composer. Locally as part of your project, or globally as a system wide executable.
Locally#
Installing Composer locally is a matter of just running the installer in your project directory. See the Download page for instructions.
The installer will just check a few PHP settings and then download composer.phar to your working directory. This file is the Composer binary. It is a PHAR (PHP archive), which is an archive format for PHP which can be run on the command line, amongst other things.
Now just run php composer.phar in order to run Composer.
You can install Composer to a specific directory by using the --install-dir option and additionally (re)name it as well using the --filename option. When running the installer when following the Download page instructions add the following parameters:
php composer-setup.php --install-dir=bin --filename=composer
Now just run php bin/composer in order to run Composer.
Globally#
You can place the Composer PHAR anywhere you wish. If you put it in a directory that is part of your PATH, you can access it globally. On unixy systems you can even make it executable and invoke it without directly using the php interpreter.
After running the installer following the Download page instructions you can run this to move composer.phar to a directory that is in your path:
mv composer.phar /usr/local/bin/composer
Note: If the above fails due to permissions, you may need to run it again with sudo.
Note: On some versions of OSX the /usr directory does not exist by default. If you receive the error "/usr/local/bin/composer: No such file or directory" then you must create the directory manually before proceeding: mkdir -p /usr/local/bin.
Note: For information on changing your PATH, please read the Wikipedia article and/or use Google.
Now just run composer in order to run Composer instead of php composer.phar.

Tell Composer to use Different PHP Version

I've been stuck at this for a few days. I'm using 1and1 hosting, and they have their PHP set up a bit weird.
If I use just php composer.phar install, then I'm using PHP 4.4.6, which is horribly insufficient. However, I can run php5.5 composer.phar install, get a little bit further, but it still fails because somewhere along the line, PHP is called again, but it fails, as it's using 4.4.6.
Is there any way to tell Composer to use the php5.5 command? Has anyone successfully gotten Composer configured on 1and1 hosting?
I'm trying to get Laravel up and running (which uses Composer). I've been able to do it on my GoDaddy domain, but not 1and1.
Ubuntu 18.04 case ... this run for me.
/usr/bin/php7.1 /usr/local/bin/composer update
Maybe this can't solve exactly your issue but probably it will help others who comes here from web search.
Just run the command to add below code to your composer.json file to set different PHP version:
$ composer config platform.php 8.0.7
"config": {
"platform": {
"php": "8.0.7"
}
}
On xubuntu I had php 7.2 as default. But needed to run composer with php 5.6.
So this worked for me:
php5.6 /usr/bin/composer
You always can use that way.
In project folder where you has composer.json file. Run the command
php7.4 /usr/local/bin/composer install
or
php7.4 /usr/local/bin/composer update
where php7.4 your specific version can be(php7.0, php5.5, php7.3 etc...)
where /usr/local/bin/composer path for system folder with composer
!!! you should have php7.4-cli
sudo apt-get install -y php7.4-cli
That way for linux/ubuntu user
Cheers ;-)
If you just need to get composer to ignore the version requirements, you can bypass using:
composer install --ignore-platform-reqs
composer is a PHP binary script and it's using Unix Shebang to define which interpreter for executing.
root#home:~# head /usr/local/bin/composer -n 5
#!/usr/bin/env php
<?php
/*
* This file is part of Composer.
*
/usr/bin/php7.1 /usr/local/bin/composer update
So if you're running composer without any specific option, it will use your PHP version at /usr/bin/env php (which is your default PHP)
We can have many versions of PHP inside your Linux and you can flexible use which PHP version for executing as you want like this way:
root#home:~# /usr/bin/php7.1 /usr/local/bin/composer update
Or just
root#home:~# php7.1 /usr/local/bin/composer
root#home:~# php7.2 /usr/local/bin/composer
root#home:~# php7.3 composer
...
To check & find all installed PHP packages, goto /usr/bin/
root#home:~# ls /usr/bin/ | grep php
php
php5.6
php7.1
php7.2
php7.3
php-config
php-config7.1
phpdbg
phpdbg5.6
phpize
phpize7.1
I too have a shared hosting account on 1&1 (ionos) and here's what I have had to do:
if you login as the root ssh account, you can create a ~/.bash_profile and add
alias php="php7.1"
alias composer="php7.1 composer.phar"
to it so that you can now use the commands you would normally use and it just works. (put composer.phar in your project folder root)
Then, make sure your laravel composer.lock file from your dev machine gets up to your project folder on 1and1 and run
composer install
Using this tip from #tobymackenzie: on shared hosts you really should just run composer install (not update!) from a composer.lock file you created on your own machine. That way the memory usage remains very low.
I still had STDIN issues with artisan commands so make sure you change the .env file to
APP_ENV=local
because having it set to production throws infinite STDIN warnings as it waits for you to type yes. At least on my account it does.
Hope this helps somebody.
In my case, Composer detected PHP version 7.2.6 but my actual PHP Version was 8.0.2 .So , I did the following steps and It was the solution for me.
Step 01:- Add below code to your composer.json file
"config": {
"platform": {
"php": "7.2.6"
}
}
Step 02:- Then, run the below command.
C:\xampp\htdocs\your project name>composer update
Try this approach
ea-php72 /opt/cpanel/composer/bin/composer
The existing answers partly do not answer the question, give suggestions that do not work or give bad advice.
The question stated:
However, I can run php5.5 composer.phar install, get a little bit further, but it still fails because somewhere along the line, PHP is called again, but it fails, as it's using 4.4.6.
Instead, I am here showing a way to test and verify the suggestions.
I wish I had a better answer myself but I am unsure what is the best solution. Personally I would go with a solution which make sure PHP is called with the correct version on the host (e.g. via an alias or setting the PHP environment correctly, running the entire operation inside a container or some other solution), regardless of Composer and add a platform php constraint.
If you don't run any scripts and just need the requirements to resolve the dependencies correctly config:platform:php would probably be your friend.
Let's say our default php version is 7.4 but our project requires 7.2.
Check your default PHP version
command line:
# shows version of default PHP
php --version
# show path of default PHP
which php
# show version of /usr/bin/env php
# /usr/bin/env php --version
Create a test script in your composer.json
"scripts": {
"php-version": "php --version"
}
Now you can test what version of PHP is used for the commands Composer
calls, e.g.
composer php-version
/usr/bin/php7.2 /usr/bin/composer php-version
In my case, both of these use my default php script (which is version
7.4). So, while the 7.2 version is used to run Composer, the scripts
called by Composer use the default command (unless you use #php instead of php1).
Now let's add the platform setting as suggested in some of the answers
"config": {
"platform": {
"php": "7.2.0"
}
}
Does not change anything for the script execution:
/usr/bin/php7.2 /usr/bin/composer php-version
# result is still 7.4
Actually, what the platform option is important for is resolving the requirements, so you should add it (in your project composer.json). It just won't solve the above problem of composer using PHP with the correct version. See also Composer docs for platform.
If you use #php instead of php, then Composer uses the PHP_BINARY2 path which is the php binary path that Composer tried to infer being executed with. See Executing PHP scripts. In this example commonly $(command -v php7.4) different to $(command -v php7.2), here $(command -v php).
PHP_BINARY is an environment variable Composer sets for its own environment (ref), similar to the predefined PHP_BINARY constant in PHP.
I had the same issue and this is how I was able to figure out how to run composer using a different PHP version on a shared hosting without breaking the system :)
Luckily, solving this issue with composer using different PHP version is dead simple.
Findings:
Default PHP was not run from /usr/local/bin or similar folder. Using the
which php
or
whereis php
would not give you the best answer.
Follow the short guide below:
First find the actual path to your composer binary itself.
On my shared hosting server, it was at
/opt/cpanel/composer/bin/composer
I believe most hosting providers using cPanel would have such path to composer.
Next, create an alias to the PHP version you want to use.
In my project, I needed php 7.4 or newer.
As mentioned earlier, the host was using cPanel and the actual default PHP version that the server uses is in the path /opt/cpanel/
You should see different versions of php in the /opt/cpanel/ (prefixed by ea-phpxx) for example, for php 7.4, it would be a folder called ea-php74 and for PHP 8.0, it would be a folder called ea-php80.
Now, be sure that php exists in a path similar to this:
/opt/cpanel/ea-php80/root/usr/bin
If you find php in the folder, then you can now alias it as folows:
alias php='/opt/cpanel/ea-php80/root/usr/bin/php'
Test that the alias is working by running
php --version
and check the php version as shown in the screenshot below:
Now, run composer as normal. For example
php /opt/cpanel/composer/bin/composer update
php /opt/cpanel/composer/bin/composer install
php /opt/cpanel/composer/bin/composer install
Remember how we found the composer binary at /opt/cpanel/composer/bin/composer. If this does not match the path to the compser binary on your server, use the appropriate one.
I hope this helps.
Happy Coding!
You could change your PATH to override the php version.
PATH="/home/user/bin:$PATH"
In /home/user/bin (or any other directory really) make a symlink named php to the php5 binary.
Another option, use a shell alias:
alias php="/path/to/php5"
I'm on a Hostgator shared account, the following worked for me:
First, find out where your desired version of PHP lives (you can start typing ea-php and hit TAB to list all available executables starting with ea-php):
which ea-php73
/usr/local/bin/ea-php73
Then, find out where composer lives:
which composer
/opt/cpanel/composer/bin/composer
Then use those to run your composer command:
/usr/local/bin/ea-php73 /opt/cpanel/composer/bin/composer install
For people using Plesk, you need the different pieces:
Get the PHP version required from /opt/plesk/php/<version/bin/php, eg /opt/plesk/php/7.4/bin/php
Get the real path of composer since /usr/local/bin/composer is a custom Plesk script by vieweing the script contents ( cat /usr/local/bin/composer ). In my case, it was /usr/local/psa/var/modules/composer/composer.phar
Put it all together:
# /opt/plesk/php/7.4/bin/php /usr/local/psa/var/modules/composer/composer.phar install
... or to make it simpler, just create a new file ( I like composer74 ) in /usr/local/bin:
cat > /usr/local/bin/composer74 to create the file
paste the following:
#!/bin/bash
/opt/plesk/php/7.4/bin/php /usr/local/psa/var/modules/composer/composer.phar
insto the terminal
Hit CTRL+D to save the file
chmod +x /usr/local/bin/composer74 to make it executable
Use it anywhere:
# composer74 install
Know this question is a bit old... but if you pull down composer into your app root:
https://getcomposer.org/download/
Instead of relying on global composer, then you can run:
php56 composer.phar {your command}
or I believe newer homstead versions would be like:
php7.1 composer.phar {your command}
https://laracasts.com/discuss/channels/laravel/run-composer-commands-with-different-php-versions
Ubuntu 18.04 case ... this works for me. Here, Composer picks the required PHP version automatically.
/opt/lampp/bin/php /usr/bin/composer install
OR
/opt/lampp/bin/php /usr/bin/composer update
php5.5 composer.phar install fails because your composer.json is telling it to run php and not php5.5, edit the file composer.json replace the php scripts references to php5.5. Example:
From:
"post-root-package-install": [
"php -r \"copy('.env.example', '.env');\""
],
To:
"post-root-package-install": [
"php5.5 -r \"copy('.env.example', '.env');\""
],
Even when doing this, 1and1 has a memory limit for scripts execution so php5.5 composer.phar install won't fail but it won't complete its execution either. You can still run the scripts post install manually.
I have deployed Laravel webapps to 1and1 without commit vendor directory, following this guide: Deploy Laravel Webapp to 1and1
I had no luck with any of above answers, I had auto scripts in composer.json so just ignoring or faking platforms just caused failed scripts etc. Setting php version in command just didn't work!
I did notice however that although running which php and php -v returned correct version which /usr/bin/env php returned the problematic version of php that composer was using. So found a very good answer here and outlined below:
Issue:
/usr/bin/env php looks for an executable named php in the current $PATH; it pays no attention to aliases, shell functions, etc. If you want it to execute php v5.3, you have to put that version in a directory under the name php, and put that directory in your PATH somewhere before the directory that contains the problematic version.
Fix:
Create new php executable folder like below with your specific php executable linked inside:
mkdir /usr/local/bin/php-overrides
ln -s /usr/local/bin/php7 /usr/local/bin/php-overrides/php
Add below to your ~/.bash_profile (or other appropriate startup script):
PATH="/usr/local/bin/php-overrides:$PATH"
https://serverfault.com/questions/579956/alias-doesnt-work-in-script-with-usr-bin-env-php
There are two ways to do it.
Tell the composer to ignore the platform requirements while running the command in the terminal.
composer update --ignore-platform-reqs
Tell the composer to ignore the platform requirements in the composer.json file in the project root directory.
"config": {
"platform-check": false,
},
We can tell Composer, what version of PHP we are supporting with our app by using the platform configuration in our composer.json file by adding the following configuration,
{
"config": {
"platform": {
"php": "5.5"
}
},
"require": {
...
}
}
Or from the command-line
composer config platform.php 5.5
i have a method to slove this problem.
export PATH=/usr/local/Cellar/php/8.0.12/bin:$PATH && composer -vvv
Temporarily change environment variables and use composer
With PHP 8 and 8.1 coming out, I have to work with a couple of versions regularly in the CLI, and the best way I found to do this was to create an alias.
Assuming you installed using brew, or already know where your version of PHP is.
Add the following to your bash profile.
alias php7='/usr/local/opt/php#7.4/bin/php'
alias php8='/usr/local/opt/php#8.0/bin/php'
If you want you can install PHP 8.1 as well with brew install php#8.1 and add another alias.
This will allow you to run php8 composer, you can do a quick test by creating an index.php file and adding phpinfo() to it.
php7 index.php | grep "PHP Version"
php8 index.php | grep "PHP Version"
While trying to install a Laravel application on my SiteGround shared hosting using SSH, I had to specify the adequate PHP bin constant prior to executing composer :
PHP_BIN=php81 composer install
Other solutions here would not work.
Must add in two places in your composer.json file to set different php version:
"config": {
"platform": {
"php": "7.4"
}
}
"require": {
"php": "^7.4",
}
You could try and copy the php and php-config files into /usr/local/bin instead. That path has a higher order of precedence and should override the /usr/bin folder without needing to disable SIP. That is what I did.
On AlmaLinux with php74 my default PHP version, php81 installed to /usr/bin/php81 and composer in location /usr/bin/composer, the following works one time: running composer using php81.
/usr/bin/php81 /usr/bin/composer install
Composer flags can be added as following:
/usr/bin/php81 /usr/bin/composer install --no-dev --no-interaction --ignore-platform-reqs
Notice these commands need to be executed from you working folder.

My Laravel installation error on localhost

I am new to Laravel, I have installed the Laravel on my localhost using
WAMP server but I am getting an error after all steps.
The errors are:
( ! ) Warning: require(C:\wamp\www\laravel/../bootstrap/autoload.php): failed to open stream: No such file or directory in C:\wamp\www\laravel\index.php on line 21
( ! ) Fatal error: require(): Failed opening required 'C:\wamp\www\laravel/../bootstrap/autoload.php' (include_path='.;C:\php\pear') in C:\wamp\www\laravel\index.php on line 21
I have used below link for Laravel installation
http://www.wikihow.com/Install-Laravel-Framework-in-Windows
I have tried to debug the issue but haven't found success in the installation.
Please let me know what is missing in installation.
You need to install Composer, open up the command prompt and cd to your directory (or hold Shift while right-clicking on your directory and clicking Open command window here) and there run composer install.
You can simplify the Laravel installation with Composers create-project command.
composer create-project laravel/laravel path
Laravel dependencies are not installed yet. That is why it is giving you this error.
https://getcomposer.org/download/
Go to this link and download composer if you haven't already.
Move the composer file to /usr/bin and rename it to just composer.
Go into the root directory of your laravel application. And run:
composer update
This will install and update all required dependencies.
In case you are on windows, which is less likely, but if you are, just download and install composer via the installer and issue the same command in you project's root directory.
Composer is PHP's dependency manager.
In the root directory of your laravel installation you will find a composer.json file. It contains the list of all your project's dependencies. If you ever need to install a package in your project, it becomes very easy. You just have to edit the composer.json file and let it know which package you need. Issuing composer update will install new package listings and update all existing ones.
just to be clear I'm not big fan of wamp.
I've just took quick look at the
http://www.wikihow.com/Install-Laravel-Framework-in-Windows
and I suppose laravel framework is not going to work best with point 11 to 14 modifications.
Baseline for laravel to work is you need to http serve /public folder in a properly configured environment (after composer install and create-project as described earlier).
If you want to take full advantage of laravel you need to often cli `php or composer (at least)` efficiently.
While using laravel I suggest installing PHP and MYSQL yourself from scratch (it really takes few minutes) and using convenient IDE (like PHPSTORM for example).
Nowadays PHP has builtin http server, so you don't need any http server in your dev environment.
So in Windows:
Install PHP and enable required libraries in php.ini
Install and configure local mysql server (easiest way installing via MySQL installer)
Start development server by invoking php.exe -S localhost:80 -t "absolute-path-to-your-laravel-installation\public" like for example C:\htdocs\laravel\public via commandLine
Enter url in your favorite browser http://localhost
Hope that will help to get you started.

Using Composer PHP on Shared Space

I'm using Bluehost and do have access to SSH, thankfully. I've also set my PHP to 5.4 in the Control Panel settings. Now, here's the two big questions that I can't seem to grasp: how do I install Composer and furthermore, after installing Composer, how do I get the dependencies included?
In this case, I am attempting to use the official Tumblr PHP Library, which has dependencies -- all of which can be found on Packagist.
I've referred to this question in which the OP is using HostGator. I have attempted to install Composer in a similar fashion and have done so with seemingly successful results. The issue, however, is that I don't know where to install it on Bluehost so I now have Composer installed in several random places on the server simply because I don't know how to navigate to find where to put it in this shared space.
I know this is the issue (i.e. it's installed in the wrong place) because when I use the composer phar files and syntax to install the packages, I get errors saying the commands don't exist.
I really hate asking for hand-holding assistance, but if someone could walk me through the proper installation of Composer on a shared space and the proper installation of a Composer package from Packagist on the same shared space, it would be much appreciated. I've dug through the Composer documentation and can't seem to find a proper guide -- if one can even exist -- for this case. At this point, I'm wondering if it's going to be different for every web host.
Once you install composer as mentioned by KLVTZ. In the bluehost environment, use the php-cli instead of php.
php-cli composer.phar install
When installing composer, the biggest problem I ran into was that Bluehost's command line php was 5.2 and composer needs 5.3+.
Fortunately, Bluehost does give you access to 5.4. You can find it at
/ramdisk/php/54/bin/php54-cli
I ended up setting up an alias to call composer.phar using the above php command and it's worked great. You can see more details on how to install composer on bluehost.
You should probably not use Composer on the remote host, but instead install it on the local machine that is used to upload your project to Bluehost. There you can manage all the stuff that is needed to fetch the dependencies, which might include having the ZIP extension enabled or having a ZIP program available, having GIT or Mercurial installed if you have to grab a version from a branch, and so on.
All these dependencies of using Composer might not be available on that remote host, and frankly: You really do not want to install these development tools on a production machine anyway, I think. Any software that potentially helps an attacker shouldn't be present if it can be avoided.
The issue, however, is that I don't know where to install it on Bluehost...
In order to fix this problem, you need to figure out where exactly your project folder is. Composer needs to be installed in that folder. If you have access to a UNIX shell, I recommend that you change your directory to that project folder
cd $_SERVER['DOCUMENT_ROOT']/project_folder/
Generally, your remote server will follow the same file directory tree as that on your local machine. However, if you are unsure as to how your file structure may be organized, you can always print working directory of your local machine:
pwd
After you have successfully located the correct file path on your shared space, simply install composer:
curl -sS https://getcomposer.org/installer | php
This will report back something like:
All settings correct for using Composer
Downloading...
Composer successfully installed to: /var/www/my_project/composer.phar
Use it: php composer.phar
You now have access to your composer.phar in your project. Let me know if you need any further help.
One problem on Bluehost is that the php command on Bluehost does not execute php-cli. So I "bypass" that by having my own php script earlier in the PATH and then forwarding the arguments to php-cli. In the same process I made script named composer which calls php-cli composer.phar directly.
So, this setup has worked for me on Bluehost:
In ~/bin I have the composer.phar and two bash scripts called php and composer. In ~/.bash_profile I have prepended ~/bin to my PATH.
~/bin/php looks as follows:
#!/bin/bash
php-cli "$#"
~/bin/composerlooks as follows:
#!/bin/bash
php-cli ~/bin/composer.phar "$#"
And the additions to ~/.bash_profile are these:
PATH=$HOME/bin:$PATH
PATH=$PATH:$HOME/.composer/vendor/bin
export PATH
(I have also added ~/.composer/vendor/bin as can be seen, this is handy for global access for some composed applications (for me that is laravel)).
Remember to source ~/.bash_profile. (Or reconnect)
I think you should do something like this.
In console
echo $PATH
Use one of these pathes
mv composer.phar {selected path}/composer
chmod +x {selected path}/composer
Now you can simply call composer everywhere
If you have composer installed in your root directory (under public_html), might be something related to PHP version. As Bluehost when chosing PHP version "Be aware that this only modifies your ~/public_html/php.ini file. If you choose to use PHP 5.4, you'll want to make sure your crons use "/usr/php/54/usr/bin/php" instead, as otherwise it will use PHP 5.2."
So you can try with the command
/usr/php/54/usr/bin/php-cli composer.phar install

Xampp / Composer / Zend Framework 2 Installation issues

Ok, so I have a composer.json file, a composer.lock file, and a composer.phar file. All the info I need to install Zend Framework I believe is in the .json file, however I have no idea what I'm doing with composer, and have no idea how to use the .phar file. If someone out there can help me out, I would be super great-full. I've been reading tutorials, and watching videos but I'm fairly new to the technical side of php. I've never worked with libraries, or command prompts, so this is all WAY over head.
Here is a start:
http://getcomposer.org/doc/00-intro.md
Step one: Download composer.phar
$ curl -sS https://getcomposer.org/installer | php
Step Two:
$ php composer.phar install
That will download all the file dependencies outlined in the composer.json file.
A couple notes:
Above assumes you are using a bash prompt (Linux or cygwin on windows) If your not using linux you can download composer.phar from getcomposer.org.
You have php in your system path meaning that when you type php in your command line it will run the php executable/binary.
