About the debugger

PHP 3 includes support for a network-based debugger.

PHP 4 does not have an internal debugging facility. You can use one of the external debuggers though. The Zend IDE includes a debugger, and there are also some free debugger extensions like DBG at or the Advanced PHP Debugger (APD).
