Installing Composer in WAMP PHP Google+ Project, PHP is not recognised - php

I am following this PHP Google+ tutorial and I am trying to install composer in my WAMP directory
C:\wamp\www\gplus-quickstart-php>curl -s https://getcomposer.org/installer | php
but I'm getting this error
'php' is not recognized as an internal or external command operable
program or batch file.
How do I resolve this problem? I already have PHP installed (via WAMP Server). Do I have to install PHP in my computer as well?

Ok a couple of things you need to do here.
First windows does not have a curl processor like unix so you need to use the other option for installing Composer
php -r "eval('?>'.file_get_contents('https://getcomposer.org/installer'));"
For this to work you need the php.exe processor to be on your path, so you have 2 options here. Either add the c:\wamp\bin\php\phpx.y.z folder to your PATH thats the bad option for WAMPServer as you can have more than one version of PHP installed and when you activate another version your PATH will still be pointing at the Old version. Or my prefered option write yourself a little .cmd file which will do it for you like this
filename = addphp.cmd
PATH=%PATH%;c:\wamp\bin\php\phpx.y.z
Put this file in a folder already registered on your path so you can run it from anywhere in a command window.
Now you will have to edit the \wamp\bin\php\phpx.y.z\php.ini file. This is similiar to the one used by php code run through the Apache web server but is only used by the PHP CLI (Command Line Interpreter)
Make sure the extension php_curl is uncommented or the above line wont work i.e. remove the ; comment symbol
extension=php_curl.dll
So now run a command window, cd into the folder that you want composer installed into and run the command above, then follow the rest of the install instructions on Install instructions

On windows, just installed composer with windows installer -> easy and with wizard - like it.
https://getcomposer.org/Composer-Setup.exe

first you have to add your php path to system
after go to php.ini and rmove ; for extension=php_openssl.dll it will be active
3 run this command in cmd :
php -r "eval('?>'.file_get_contents('https://getcomposer.org/installer'));"

If using phpstorm you can download composer using their built in composer option in the tools menu.
You can run it from CLI by locating your php.exe, e.g
C:\wamp\bin\php\php7\php.exe composer.phar install

No idea if anyone will answer this late but I'm having issues with this. I created the .cmd file and put in the path as suggested. I put this file in my wamp\www\sitename folder. Is that not what you mean when you say putting it in a "registered path folder"? After creating the file, and running the code it still says php not recognized.

First, to get php into your path see my answer here
Installing composer is explained nicely here (code below just for illustration. Be sure to get latest from the link)
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
A quick check to confirm it worked:
$ php composer.phar --version
Composer version 1.2.1 2016-09-12 11:27:19

zsh: command not found: php. PHP is installed and working with MAMP

I am trying to use composer to install a google client library, but cannot install composer or use php on the command line.
I am using php 8.0.8 with MAMP and it is working fine, so I know it is installed.
If I type php in the terminal, I receive the command not found message. Thinking it could be an environment variable, I have tried navigating to the php folder /Applications/MAMP/bin/php/php8.0.8/lib/php and tried the php command again, but still get the same error
I am using a Mac running Monterey
Change default Mac OS X PHP to MAMP's PHP Installation and Install Composer Package Management
Instructions to Change PHP Installation
First, Lets find out what version of PHP we're running (To find out if it's the default version).
To do that, Within the terminal, Fire this command:
which php
This should output the path to the default PHP install which comes preinstalled by Mac OS X, by default it has to be (Assuming you've not changed it before):
/usr/bin/php
Now, We just need to swap this over to the PHP that is installed with MAMP, which is located at /Applications/MAMP/bin/php/php5.4.10/bin (MAMP 2.1.3)
To do this, We need to edit the .bash_profile and add the MAMP version of PHP to the PATH variable.
Follow these simple steps:
Within the Terminal, run vim ~/.bash_profile
Type i and then paste the following at the top of the file:
export PATH=/Applications/MAMP/bin/php/php5.4.10/bin:$PATH
Hit ESC, Type :wq, and hit Enter
In Terminal, run source ~/.bash_profile
In Terminal, type in which php again and look for the updated string. If everything was successful, It should output the new path to MAMP PHP install.
In case it doesn't output the correct path, try closing the terminal window (exit fully) and open again, it should apply the changes (Restart in short).
Install Composer Package Management
Now you can fire the command to install the composer globally (So you can access it from anywhere):
$ curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
You can verify your installation worked by typing the following command within the Terminal:
composer
It'll show you the current version and a list of commands you can use if the installation was successful.

How to change PHP version used by composer

I want to use another php version on my machine than the one already installed using WAMP (2 PHP version installed).
The composer installed uses PHP 5.6
A new project requires PHP7.0.
Whenever I choose PHP 7 from the control panel of WAMP and then run php -v it still printing PHP5.6 (CLI)... instead of PHP7.
How can I use PHP7 without reinstalling the composer again?
You can change php version of composer without uninstalling it, follow these steps :
Search for system environment variables in cortana.
Click on the button "Environment variables".
Under "System variables" select path and click on edit, you will see one entry like this "C:\wamp\bin\php\php5.6.13".
Just change this to the folder name of the php located at your wamp/bin/php7.1.9, here php7.1.9 is folder name.
Replace php5.6.13 with bin7.1.9, it will look like these "C:\wamp\bin\php\php7.1.9", just click ok on all the boxes.
You are done.
To verify, first close all the cmd windows, than open cmd and type php -v, press enter and you should see php7.1.9.
If you don't see change in php version than just restart your pc and run php -v again in cmd , it will work.
I'm assuming Windows if you're using WAMP. Composer likely is just using the PHP set in your path: How to access PHP with the Command Line on Windows?
You should be able to change the path to PHP using the same instructions.
Otherwise, composer is just a PHAR file, you can download the PHAR and execute it using any PHP:
C:\full\path\to\php.exe C:\full\path\to\composer.phar install
If anyone is still having trouble, remember you can run composer with any php version that you have installed e.g. $ php7.3 -f /usr/local/bin/composer update
Use which composer command to help locate the composer executable.
I found a very easy way to switch php versions:
Search for system environment variable
Click on "Environment variables"
Under "System variables" select path and click on edit
Move the PHP version folder you want to use before the other one.
So for example: php 7.0 will now be used:
Close all windows by clicking "OK"
Close all the cmd windows, than open cmd and type php -v
You will see the correct php version loaded now:
Another possibility to make composer think you're using the correct version of PHP is to add to the config section of a composer.json file a platform option, like this:
"config": {
"platform": {
"php": "<ver>"
}
},
Where <ver> is the PHP version of your choice.
Snippet from the docs:
Lets you fake platform packages (PHP and extensions) so that you can emulate a production env or define your target platform in the config. Example: {"php": "7.0.3", "ext-something": "4.0.3"}.
This is what happens in my case. I hope this may help to someone have same situation. I'm using macOS Monterey with MAMP.
I linked the php 7.4 using ~/.profile file. So the terminal it says I'm using php 7.4. However, still my composer giving an error saying i'm using php 7.3.
So I check the php path using
which php
This gives me the /usr/local/bin/php as my php cli location. So I remove the file and made a symlink to my php7.4 and now working perfectly.
sudo rm -rf /usr/local/bin/php
sudo ln -s /Applications/MAMP/bin/php/php7.4.21/bin/php /usr/local/bin/php
I found out that composer runs with the php-version /usr/bin/env finds first in $PATH, which is 7.1.33 in my case on MacOs.
So shifting mamp's php to the beginning helped me here.
PHPVER=$(/usr/libexec/PlistBuddy -c "print phpVersion" ~/Library/Preferences/de.appsolute.mamppro.plist)
export PATH=/Applications/MAMP/bin/php/php${PHPVER}/bin:$PATH
Old question I know, but just to add some additional information:
WAMP is used only on Microsoft Windows Operating Systems.
Changing the version of PHP used through the left-click -> PHP -> Version menu changes the version used by Apache to server your site.
Changing the version of PHP used through the right-click -> Tools -> Change PHP CLI Version menu changes the version used by WAMP's PHP CLI.
Note: It is important to understand that the "PHP CLI Version" is used by WAMP's own internal PHP scripts. This "PHP CLI Version" has nothing to do with the version you wish to use for your scripts, Composer or anything else.
For your scripts to work with the version you require, you need to add it's path to the Users Environmental Path. You could add it to the Systems environmental Path but the Users Path is the recommended option.
From WAMP v3.1.2, it would display an error when it detect reference to a PHP path in the System or User Environmental Path. This was to stop confusion such as you were experiencing. Since v3.1.7 the display of this error can now be optionally displayed through a selection in the WampSettings menu.
As indicated in previous answers, adding an installed PHP path (such as "C:\wamp64\bin\php\php7.2.30") to the Users Environmental Path is the correct approach. PS: As the value of the Users Environmental Path is a string, all paths added must be separated with a semi-colon (;)
After experiencing the exact same problem (IE: Choosing which version of PHP I wanted Composer to use), I created a script which could easily and rapidly switch between PHP CLI Versions depending on what project I was working on.
The Windows batch script "WampServer-PHP-CLI-Version-Changer" can be found at https://github.com/custom-dev-tools/WampServer-PHP-CLI-Version-Changer
I hope this helps others.
Good luck.
After a long search on the internet and finding many unrelated answers / ones that did not work for me, Here is what worked for me.
Those who are in shared hosting know that bin directory is write-protected and running sudo commands or any system-wide command is not allowed.
There's two ways of solving this:
Run the command directly on your project folder selecting the appropriate PHP version you need.
ea-php80 /opt/cpanel/composer/bin/composer update
To get available PHP on your server type ea-php and hit TAB to see a list.
make an alias to composer
Run this command to edit/make this file nano ~/.bashrc
Inside that file, put alias composer="ea-php80 /opt/cpanel/composer/bin/composer"
This gives you the flexibility to run composer commands as usual without those long trailing strings
If you are using Windows, all you have to do is change the path to php.exe in the composer.bat file located in: "C:\ProgramData\ComposerSetup\bin".
In my case I include paths to all php versions, whenever I need to run a project on a specific php version, I just move the required path to the top (using these buttons in the right) and then close all the terminals and restart my wampp server.
The path with listing in the will be selected as your php version by windows
This is the simplest solution I think.
If you still facing the problem after changing Environment variables in windows, try to delete directory or just rename directory of your old php.
I've done it and it's work.
I will assume that you need this because a requirement to have multiple php versions installed to handle multiple projects.
If this is the case a prefer to run directly the php desired bin pointing to the executable script of composer, for example, in my case I have php 8.1 and 7.4, my main php version configured for CLI is 8.1, but I want to run composer with 7.4 in some projects, so I run this command:
php7.4 -f /usr/local/bin/composer install
Where php7.4 is the bin installed and my global composer script is in /usr/local/bin/composer
From there, you can make an alias like this to facilitate things: alias composer7.4='php7.4 -f /usr/local/bin/composer ' so next time you need to run composer with php#7.4 you only need to run: composer7.4 install
Came here by the title, but the question specifies WAMP; which this may not easily apply to. So, in my case - using a Mac.. so more like a MAMP - if you have brew and the below versions installed, this could help - and composer picks it up.
brew link --overwrite --force php#8.1
php -v
#PHP 8.1...
brew link --overwrite --force php#7.4
php -v
#PHP 7.4...

Why doesn't my Mac OS X have a php.ini file? How should I get it so that I can download and install composer?

I appear to have problems with a php.ini file that doesn't exist, or at least not in the right place.
My ultimate goal is to create projects with Laravel on my Macbook Pro (Mac OS X). To install Laravel I have to install Composer (https://getcomposer.org/). To download Composer I am instructed to run the following in Terminal:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
Terminal responds:
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:
The detect_unicode setting must be disabled.
Add the following to the end of your php.ini:
detect_unicode = Off
A php.ini file does not exist. You will have to create one.
If you can not modify the ini file, you can also run php -d option=value to modify ini values on the fly. You can use -d multiple times.
Now, it is my understanding that all Macs have PHP running by default. I seem not to. I really don't understand why, there is no php.ini file where it should be (/etc). I've also made plenty of websites using MAMP, which includes PHP. My guess is that Composer doesn't search for the php.ini used for MAMP, but requires it in etc/. But how do I get a php.ini file in there safe?
I've been stuck at getting Composer and Laravel to work on my Mac for a long time now. Thanks for taking the time to help me. It means a lot.
Generally php.ini is located in /etc, you can check where it might be by doing the following command within Terminal:
php -i | grep php.ini
Output:
Configuration File (php.ini) Path => /etc
If you don't have one then I would take the advice of the instructions and create one. There is a "default" one that you can copy to create it:
cp /etc/php.ini.default /etc/php.ini
I've worked on many projects in laravel on OSX and honestly I suggest you not to set a custom enviroinment, as suggested in documentation, for development you could use:
1) Homestead : based on Vagrant, multiplatform (it needs virtualbox or vmware)
2) Valet : specific for osx (should be faster)
For both you'll get Php, Nginx, mysql, redis, composer, node and so much more completely configured.
I've always used Homested and following the guide you get a complete dev env in minutes

how to create autoload under vendor directory for php rabbitmq

I m new to php and rabbitmq in debian(Linux). I have installed xampp, rabbitmq and also installed composer.phar in project directory using below command
/opt/lampp/htdocs/rabbitmq_demo# curl -s https://getcomposer.org/installer | /opt/lampp/bin/php
Now I use Composer to install the dependencies of the project using below command
composer.phar install
but it thrown an error as below
bash: php: command not found
I have preferred the link https://getcomposer.org/doc/00-intro.md
I want to prepare autoload.php
Please help me to create autoload under vendor directory.
You do not have a php cli program installed on your computer or it is not in your current $PATH variable. Please install PHP first or correct your $PATH environment variable.
Once you have this, run the composer.phar install again. This will download all dependencies listed in your composer.json file. Once the program completes, you will have a file ``vendor/autoload.php`. You can just require this file at the beginning of your own script and everything will be taken care of.
You need to add the path to the PHP command line (CLI) in the XAMPP install, to your bash environment. (You'd think the installer would do this!)
The XAMPP PHP CLI on Debian is at /opt/lampp/bin/php
So you need to add /opt/lampp/bin to your $PATH environment variable.
See this answer for the various options in modifying your path depending on who you want to be able to run PHP.
/etc/login.defs
/etc/environment
/etc/profile
~/.bashrc
In one of those files, you append to the path thus:
PATH=$PATH:/opt/lampp/bin
and re-login.

Update composer dependencies from command line

I am currently working with symfony2 and I want to launch to download the libraries I need. I know the command in linux is "$ ./composer.phar update --dev" however when I run this in windows it prompts whether I should open the file with the windows explorer or not. I currently have composer.phar installed on windows but I am having trouble launching it. How would I be able to update my symfony2 folder with the dependencies I need. Thank you.
In CMD:
php C:\ProgramData\ComposerSetup\bin\composer.phar self-update
The problem is that Windows don't know how to open .phar files. You need to execute them using php interpreter php composer.phar update and the php interpreter(php.exe) must be accessible on PATH.
You could use command php -v to check if your php is accessible from command line.
Go to C:\ProgramData\ComposerSetup\bin\composer.phar
In CMD write php composer.phar (update) or (self-update)
1: Open cmd
First go to your work directory like if you have wamp then c:/wamp/www.
Then enter composer if you can see list of composer command then its good.
Now type "composer self-update".
5: Next you can see the process.
This worked for me on my Centos server
sudo -u nginx php composer.phar update
