Xdebug has various configuration options which we can use to let the PHP interpreter reach out to PhpStorm. These parameters have to be passed to the PHP interpreter using the -d command line switch. A more convenient way will be to set an environment variable so we don't have to provide the -d switches all the time.

Using PHP command line switches

To start our script with debugging we have to:

1. Set an environment variable that would tell XDebug to connect to IDE:

   Code Block
   Windows: set XDEBUG_CONFIG="idekey=123"   Linux / Mac OS X: export XDEBUG_CONFIG="idekey=123"

   Here idekey should have a random value.

2. Launch PHP with several switches:

   Code Block
   php -dxdebug.remote_enable=1 -dxdebug.remote_mode=req -dxdebug.remote_port=9000 -dxdebug.remote_host=127.0.0.1 -dxdebug.remote_connect_back=0 path/to/script.php

    

   You might use 10.0.2.2 instead of 127.0.0.1 with Vagrant (see related SO question).

    

Using an environment variable

To start our script with debugging, we can set an environment variable that configures Xdebug:

Windows:
set XDEBUG_CONFIG="remote_enable=1 remote_mode=req remote_port=9000 remote_host=127.0.0.1 remote_connect_back=0"

Linux / Mac OS X:
export XDEBUG_CONFIG="remote_enable=1 remote_mode=req remote_port=9000 remote_host=127.0.0.1 remote_connect_back=0"

Next, we can start our script like we would normally do:

php path/to/script.php
