Xdebug is a php extension which provides debugging and profiling capabilities.[1] It uses the DBGp debugging protocol.

The debug information that Xdebug can provide includes the following:

  • stack and function traces in error messages[2] with:
  • full parameter display for user defined functions
  • function name, file name and line indications
  • support for member functions
  • memory allocation
  • protection for infinite recursions

Xdebug also provides:

  • profiling information for PHP scripts[3]
  • code coverage analysis
  • capabilities to debug your scripts interactively with a debugger front-end.[4]

Xdebug is also available via the PECL library.[5]
