Global installation of PHP tools with Composer

The Composer package manager along with the Packagist repository site is quickly becoming the defacto PHP package management system.

One feature I found out about recently is that you can install packages globally rather than locally into your project. I think that this is most useful for development tools, such as PHPUnit which are then available everywhere.

To install a composer package globally, you run the usual require command, but with the addition of the global modifier. So to install PHPUnit, you would run:

$ composer global require phpunit/phpunit
$ composer global require phpunit/dbunit
$ composer global require phing/phing
$ composer global require phpdocumentor/phpdocumentor
$ composer global require sebastian/phpcpd
$ composer global require phploc/phploc
$ composer global require phpmd/phpmd
$ composer global require squizlabs/php_codesniffer

This will install PHPUnit and all its dependencies into the ~/.composer/vendor/ directory and, most importantly, the phpunit CLI tools are installed into ~/.composer/vendor/bin/.

Simply add this directory to your PATH in your ~/.bash_profile (or ~/.bashrc) like this:

export PATH=~/.composer/vendor/bin:$PATH

and phpunit is now available on your command line.

To keep your tools up to date, you simply do this:

composer global update

To remove a package, you edit ~/.composer/composer.json and then run composer global update.

  1. Hey, thx for the hint!

    Unfortunately i can't use the "phpunit" command and i get this error:

    -bash: vendor/bin/phpunit: No such file or directory

    When i run phpunit with the full directory "~/.composer/vendor/bin/phpunit" it works? Am I missing something here?

    Thanks and cheers

  2. Global for the *user* you mean. What about global to the machine? If you have a build machine for instance that always needs phpunit, phpmd, etc..

    I guess that's why pear is still around, unfortunately it seems some authors are not keeping pear packages/release in step with composer.

  3. I was stuck after installing a composer package globally, but I was unable to run it. This was just the solution I was after. Thanks!

    The only step you forgot to mention was to run 'source ~/.bash_profile' to reload the profile config and be able to call the global package successfully.

  4. I installed the phpunit as mentioned above, but when i run the test, il returns always un error that PHPUnit_Framework_TestCase not found

    Anyone has an idea?

  5. I usually install a global version of phpunit as well as a local one. The reason for this is that I am often using the local version like `composer tests` since I have a mapping in my composer.json file for `php -n ./vendor/bin/phpunit tests'`, but I also have setup a pre-commit hook and in this one I need to use the global package since I am only commiting code that has no development packages installed.
