# XDebug and PHP-FPM configuration

Configuring XDebug on a PHP-FPM powered server.

## The problem

I’ve set up a new local development environment following this excellent guide and all went smooth until I could not debug my code using XDebug.

php --version

The above command does show that XDebug is installed and running but the until then working PhpStorm configuration stopped working.

## Shut door

The issue lies in the port that’s used by XDebug by default to connect to servers: the 9000 one; PHP-FPM is listening on that port already and the following command will show it

XDebug allows for the configuration of another port to use so that’s not an issue; I’ve modified my XDebug configuration file to use the port 9009 in place of the default one

[xdebug]
zend_extension="/usr/local/opt/php56-xdebug/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_host="localhost"
xdebug.remote_handler=dbgp
xdebug.remote_port=9009
xdebug.remote_autostart=1

and made sure that PHPStorm will listen on that. The game is done.
