To signal the debugger to initiate connections, Xdebug will look whether the Through a browser, or on the command line, such as when running unit tests. Which trigger to use depends on whether you're debugging a PHP application Present, although it's possible to instruct the debugger to always initiate aĭebugging session by setting xdebug.start_with_request to yes.

In the default configuration, the debugger activates if a 'trigger' is Make sure that the host running PHP/Xdebug can connect to your IDE with theĬonfigured IP address and port, and that there is no firewall or other softwareīlocking an incoming connection. Of the machine that runs your IDE, and with xdebug.client_port the TCP port. With xdebug.client_host you can select the IP or hostname In more complex set-ups you need to configure the host and port that XdebugĬonnects to yourself. Way of set-up if you are sharing a development server among you and your team HTTP headers to find out the IP address of the host that initiated theĭebugging request, and use that IP address to connect to. Xdebug.discover_client_host setting to 1. Your browser on the same host as your IDE, then you set the If PHP/Xdebug run on a different machine in the same sub-net, and you run To, as it is Xdebug that initiates the communication to the IDE, and not If PHP/Xdebug run on a different machine, virtual host, or in a DockerĬontainer, you need to tell Xdebug where to make the debugging connection Same host, this is all you need to configure on the PHP and Xdebug side.

There isĪlso a simple Command Line Debug Client available as part of the Xdebug project,īut it is strongly recommended that you use an IDE for debugging. This protocol is supported by nearly every PHP IDE (including Visual StudioĬode and PhpStorm), and also by text-based editors. Therefore you also need to configure an IDE that knows how to talk to Xdebug Xdebug interacts with IDEs to provide step debugging functionality, and

Xdebug's step debugger allows you to interactively walk through your code toĭebug control flow and examine data structures.
