Welcome to "Learn Xdebug!" The Xdebug docs are in limbo as Derick prepares for the release of Xdebug 3 in December, so here are some easy options for you to learn Xdebug.
The goal here is for it to be easy for you to learn Xdebug, and also for us to collect and standardize learning materials for Derick to use for building the new docs.
Xdebug is a PHP extension that adds a step debugger, a
profiler, PHPUnit code coverage; adds stack traces for Notices, Warnings, Errors, and Exceptions;
and upgrades var_dump()
. It's created and supported by Derick Rethans.
