APD: Advancd PHP Debugger

APD is the Advanced PHP Debugger. It was written to provide profiling and debugging capabilities for PHP code, as well as to provide the ability to print out a full stack backtrace. APD supports interactive debugging, but by default it writes data to trace files. It also offers event based logging so that varying levels of information (including function calls, arguments passed, timings, etc.) can be turned on or off for individual scripts. See http://www.php.net/manual/en/ref.apd.php for more information.

Please note that php-apd RPM conflicts with php-accelerator and php-APC.
