composer create-project dg/php-extensions-finder 

Or install it globally via:

composer global require dg/php-extensions-finder 

and make sure your global vendor binaries directory is in your $PATH environment variable.

  Check for required PHP extensions with Composer

  Thanks to creation the Composer PHP Dependency manager, using and managing 3rd party libraries has become a breeze. Gone are the days of committing dependencies and manually keeping things up to date. Additionally using Composer removes the possibility of someone making changes to a 3rd party library and committing it. Don’t do it! Recently I began adding Composer to some of my legacy projects and refactoring dependencies like PHPMailer over to Swiftmailer. Also thanks to PHP 5.4 and its built in web server reformatting things to make development easier. Throughout a projects lifecycle I may work on multiple different systems. Maybe my laptop when working on-site or my own using Windows or Linux. The awesomeness of being able to run php composer.phar install after updating my sources just makes me smile.

  That brings me to today and preparing to deploy a new Linode instance. After provisioning my new server, grabbing the sources and running the Composer install I sat back, put my feet up on the desk and thought life is just grand.

  Houston we have a problem

  Roughly 30 minutes later I get a notification from NewRelic informing me that my error rate is at 10%, Doh! So back to the server logs to see what’s up and find.

  PHP Fatal error: Class 'Imagick' not found

  Well that explains things. Just need to install the PHP Imagick module and we are back in business. But how can I make sure this doesn’t happen again? I could configure a build system using Phing or Ant, or just write a bash build script to automate it in the future. Both would work abet be overkill for the scope of the project. That’s when I turned to composer and found information on Platform packages.

  Composer Platform Packages

  Composer has platform packages, which are virtual packages for things that are installed on the system but are not actually installable by Composer. This includes PHP itself, PHP extensions and some system libraries.

  Woo hoo! That’s exactly what I was looking for. To validate the availability of PHP extensions, all that is needed is to preface its name with ext- and add it to the requre section of the package.json file.

  Example

   "name": "composer/example", "require":  "php": ">=5.4.0", "swiftmailer/swiftmailer": "5.3.0", "ext-imagick": "*" > >

  Note: Notice the specified version is set to *. The Composer docs state that:

  Versioning can be quite inconsistent here, so it’s often a good idea to just set the constraint to *.

  Testing it out

  Now to test I locally removed the imagick extension and ran composer again which returned:

  Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested PHP extension ext-imagick * is missing from your system.

  Conclusion

  With that in place now I can track these dependencies in the future. It would be nice to have it handle the installation of the missing extensions but at least knowing makes things a whole lot easier.
