How composer check php version?
Solution 1
Composer can tell you what version of PHP it's running on, if you specify debug verbosity -vvv
.
I like to run it with the about
command, since the output is relatively short.
composer -vvv about
Example output:
... Running 1.8.5 (2019-04-09 17:46:47) with PHP 7.3.5 on Darwin / 18.6.0 ...
Edit: This has gotten more interest than I expected, so here's a version with cleaner output:
composer -vvv about 2>&1 | grep "PHP"
Solution 2
On MacOs X the default installation of php resides in /usr/bin. If you upgrade your php it will most likely be installed somewhere else (like /usr/local/php5), or if you use MAMP or something else it will be elsewhere. Just make sure that the first occurrence of php when traversing your PATH is the same as the version your webserver is using. (like have /usr/local/php5/bin before /usr/bin in your PATH). That will solve your problem.
Solution 3
If you used a package install method, such as apt-get on Ubuntu, chances are that the executable will include a "shebang" pointing to the specific php that should be used to run that specific composer file.
When using the command composer
the cli will first resolve which binary to use. By running which composer
you can find what binary that is.
$ which composer
/usr/bin/composer
Once you know that, you can open the file, for instance using vim: vim /usr/bin/composer
(generally it takes super user access to modify binaries so you shouldn't be able to mess composer up doing that).
On the first line of the composer binary should be a shebang, possibly looking like #!/usr/bin/php
that would instruct the composer executable on how it should run.
You can then call that php binary directly to verify its version:
/usr/bin/php -v

I just wondering how composer check which php to use when check for requirements. I use MacOS and in terminal type:
composer require phpunit/phpunit
the result is something like:
Problem 1 - phpunit/phpunit 5.0.4 requires php >=5.6 -> your PHP version (5.5.27) or "config.platform.php" value does not satisfy that requirement....
When I check php version:
php -v
The result is:
PHP 5.6.10 (cli) (built: Jun 12 2015 14:08:56) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies with Xdebug v2.2.5, Copyright (c) 2002-2014, by Derick Rethans
Which is:
which php
php: aliased to /Applications/MAMP/bin/php/php5.6.10/bin/php
Can someone explain this. Thanks in advance!

samerivertwice over 3 yearson Centos7 php -v and phpver all indicate 7.4 but installing Craft, Composer is running with php5. Any ideas why? I'm guessing there's a composer environment variable set somewhere.

Eduardo over 3 yearsHello, i have been getting some issues regarding the version of PHP, I couldn't use a package because the version was different, is there a way to change the version using this location or better yet, how to tell composer to use the version from another place? For example the one where 7.4 is installed. Thanks!! Edit: Im using Laravel 8
