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...
I am trying to install Symfony 2.7 as instructed by the manual.
When I open CMD (I am running it as an administrator in Windows 8.1) the default path is C:\Windows\System32. I have tried running the command specified in the documentation there (c:\> php -r "readfile('http://symfony.com/installer');" > symfony), as well as in the root directory, both give me the same error.
I am using WAMP, the appache rewrite module and php_xls are activated.
I've also added the following to the PATH in the environment variables: ;C:\wamp\bin\php\php5.2.5;C:\wamp\bin\mysql\mysql5.0.45\bin
After having added it, I rebooted the computer and still nothing worked. How can I install Symfony 2.7?
Here is the solution to your original problem:
You just have to make sure that the path to your php executable is correct when you add it to your PATH environment variable. This path is probably related to the version of PHP you have. You should be able to find this path by navigating inside your wamp installation and looking for the php folder and binary. In your case, this would be C:\wamp\bin\php\php5.5.12
However, for the new problem you have...
However, I get the error The directory name is invalid when I execute
the following command: c:>projects\ php symfony
You just have to make sure that your PATH is updated with the correct path for your php, and then do this from C:>
php projects\symfony
Note that php is the executable and projects\symfony is the path to the symfony file.
I'm using Yii and a WampServer 2.4 64bit.
I installed PEAR and PHPUnit manually.
I can only run the commands PHP, PEAR or PHPUnit in the install folder:
E:\wamp\bin\php\php5.4.12
But I want to execute the commands PHP and PHPUnit from here:
E:\wamp\www\repo\project\protected\tests
So I added the path to my php.exe to my PATH environment variable like this:
;E:\wamp\www\bin\php\php5.4.12
But I can't call php -v on E:\wamp\www\repo\project\protected\tests without the error message, that the command is unknown.
I followed a lot of tutorials how to add php or PHPUnit to my environment variable PATH but nothing is working.
So I realy realy hope,someone can explain me where my mistake is.
You probably added a "www" that is not needed in your PATH variable
;E:\wamp\bin\php\php5.4.12
seems the correct version to me.
I am currently running Wampserver with multiple PHP versions (5.3.8, 5.4.3). Wampserver easily allows you to switch back and forth between the php version you want apache to use. However, I'm having trouble dealing with multiple versions from the CLI. I have projects that require the command line, but some are compatible with php5.4, while some are not.
Is there a way to create some type of "alias" in Windows that allows me to specify which version of PHP to use on the command line .. I.E: "php54 cache:clear", "php53 cache:clear" ??
Thanks!
I am doing something like below.
ex. I have two php version , PHP 5.6 and PHP 7.3
I have wamp environment so I have done as below
so I have copied D:\wamp\bin\php\php7.3.6\php.exe to D:\wamp\bin\php\php7.3.6\php7.exe
and I have copied D:\wamp\bin\php\php5.6\php.exe to D:\wamp\bin\php\php5.6\php56.exe
Then I have added both to environment variable path like below.
now you need reopen the cmd and you can use command something like below
php56 -v
php7 -v
You can also run command refreshenv to reload environment variables in opened cmd.
If you want change default php version, you can move paths as below.
ex if you want php 7.0.23 as default instead of php 7.3.6
see screenshot for example
In above screenshot I have move php 7.0.23 above the all other php verions (php 7.3.6 and php 5.6.31).
I hope this will help.
Its quite simple really.
Create yourself a batch file to add php to the path, place that file in one of the folders that is currently on your PATH so you can run it from anywhere.
Then whenever you are in any folder that has CLI scripts in it run the batch file
Example batch file:
Lets call it PHPPATH.CMD
path=%path%;c:\wamp\bin\php\php5.4.11
php -v
Now if you want to use another version of the PHP CLI just change the batch file or if you are feeling clever make the batch file accept a paramter so you can specify the version of php you want on the path.
If you are able to do so, just create aliases:
alias 'php56'='/Path/To/php5.6/bin/php';
alias 'php55'='/Path/To/php5.5/bin/php';
If not, create links in a seperate directory that point to the binaries.
php56 is a link to /Path/To/php5.6/bin/php
php55 is a link to /Path/To/php5.5/bin/php
put these into /Seperate/Path/ and add '/Seperate/Path/' to %PATH%
Hope this helps
I've searched how to do it really easily without changing the environment variable path with the command line (because it's character limited) and find this solution (only on windows 10) :
in your environment variable path , change [D:\wamp64\bin\php\"your php version"] in [D:\wamp64\bin\php\php]
then create a junction between your php version directory and D:\wamp64\bin\php\php by running this command in cmd as administrator :
mklink /J D:\wamp64\bin\php\php D:\wamp64\bin\php\php"your php version"
then you can use this batch file
echo off
::read the actual php version
::(read the second word of php -v output )
for /f "tokens=2" %%i in ('php -v') do (
::if actual version is 7.4.0 I want 7.4.1
if "%%i"=="7.4.0" set phpV="7.4.1"
::if actual version is 7.4.1 I want 7.4.0
if "%%i"=="7.4.1" set phpV="7.4.0"
)
::delete the old junction
rmdir "D:\wamp64\bin\php\php"
::create a new one to the version I want
::!!!!!!!!!!!!!!!!!!! paths must not contains spaces
mklink /J D:\wamp64\bin\php\php D:\wamp64\bin\php\php%phpV%
now you can run your batch file in your cmd and don't even have to restart it after.
My system has two PHP interpreters. One came bundled with the OS and the other I installed via the XAMPP package. All of my PHP extensions are applied to the XAMPP installation but PHPUnit seems to only run the version of PHP that came with my machine.
Does anybody know of a way I can configure or rebuild PHPUnit so that it uses my XAMPP PHP interpreter exclusively?
For Mac/Linux, the first line of the phpunit script with starts with
#!/usr/bin/php
change that to
#!/Applications/XAMPP/xamppfiles/bin/php
or whatever other php interpret you want to use.
Find the folder you installed PHPUnit in. There should be a file called phpunit.bat. It should have a line that reads something like
set PHPBIN="C:\php\php.exe"
%PHPBIN% "C:\php\phpunit" %*
Change it to read
set PHPBIN="C:\xampp\php\php.exe"
%PHPBIN% "C:\xampp\php\phpunit" %*
Or whatever the path to your PHP executable is
Since modifying phpunit file did not work for me because of phar signature errors, I was running phpunit with different php version by calling interpreter explicitly (on Linux):
php7.1 /usr/local/bin/phpunit
php5.6 /usr/local/bin/phpunit
Following the example with XAMPP, full path to php interpreter could be provided:
/Applications/XAMPP/xamppfiles/bin/php /usr/local/bin/phpunit
In agreement with Thomas' statement, additionally there's a line further below
if (strpos('/Applications/MAMP/bin/php5.3/bin/php', '#php_bin') === 0) {
set_include_path(dirname(__FILE__) . PATH_SEPARATOR . get_include_path());
}
That I've been told you're also supposed to change to reflect the PHP you're interested in using
(I've set mine to MAMP obviously)
I've switched back and forth from 5.2 and 5.3 a lot recently :)
This applies to phpunit installed using Homebrew on Mac OS 10.9. I’ve editing the file located at /usr/local/Cellar/phpunit/4.2.6/bin as seen below. CAVEAT: I don’t know how Homebrew will handle this on a PhpUnit update, but for now it’s working to be able to select the php version that PhpUnit is using for it's testing.
#!/usr/bin/env bash
php=/Applications/MAMP/bin/php/php5.3.14/bin/php
#php=/Applications/MAMP/bin/php/php5.4.4/bin/php
/usr/bin/env $php -d allow_url_fopen=On -d detect_unicode=Off /usr/local/Cellar/phpunit/4.2.6/libexec/phpunit-4.2.6.phar $*
On Windows, this may be achieved using a similar approach to the ones mentioned in other replies.
In your /path/to/composer/phpunit directory, open the phpunit file in an editor. The first line should look like this:
#!/usr/bin/env php
Simply download your desired version of PHP for Windows, place the contents of the ZIP file somewhere to your liking, and reference the fully quantified path to the php.exe file, instead of just php. Like so:
#!/usr/bin/env /c/misc/php-5.5.9-nts-Win32-VC11-x86/php.exe
In my case, I put it in /c/misc/php-5.5.9-nts-Win32-VC11-x86/, which corresponds to C:\misc\php-5.5.9-nts-Win32-VC11-x86\ using Windows path syntax.
Remember to verify that the correct php.ini file is being used (php --ini or in a script file php_ini_loaded_file()).
