Install PHP Modules

Xdebug comes pre-installed. To enable xdebug you need to add a couple environment variables:

• ENABLE_XDEBUG=1 This will add the xdebug.ini to your php extensions
• XDEBUG_CONFIG=remote_host=you.local.ip.here Sets an xdebug remote host environment var. This is usually your actual local computers IP.
• PHP_IDE_CONFIG=serverName=NameUsedInPhpStormServerConfig This is an example of how to use this in PhpStorm. You configure a server in php storm with a name, set that in this var.
