Projects / Xdebug


The Xdebug PHP extension aids script debugging by providing a lot of valuable information, including stack and function traces in error messages, memory allocation traces, and protection from infinite recursions. Xdebug also has a built-in debugging server which you can access with a debug client to debug your scripts remotely. Stepping, accessing data, and examining stacktraces are a few of the remote capabilities.
