IntelliJ IDEA can validate your configuration of Xdebug or Zend Debugger and tell you if some setting is missing (for example, xdebug.remote_enable) or inconsistent with other settings. When configuring the PHP interpreter for a project, IntelliJ IDEA informs you whether a debugger is installed in your local PHP development environment and reports on the Xdebug or Zend Debugger version used. For details, see Configuring a Debugging Engine and Enabling PHP Support.
You can also validate the debugger setup in a remote environment.
