How can I debug my php code?

Debugging PHP code in Cobalt RAQ4

• Cobalt RAQ4 comes with Apache/PHP4.1.2 pre-packaged. How do we debug PHP code in this system? The PHP is compiled with --dable-debug flag. My situation is that, I have some PHP scripts that runs just fine, but some others just simply gives Segmentation Violation when run either from web-browser or from command line. How do I go about debuggint this problem? -Srinivas

  Hi srinivas, According to the php.net site, PHP 3 includes support for a network-based debugger. PHP 4 does not have an internal debugging facility. (Source :: http://www.php.net/manual/en/debugger.php) However, you need not despair. There are external debuggers available. I've listed a few - DBG (Free) http://dd.cron.ru/dbg/ The DBG Php Debugger is a comprehensive software tool that helps you debugging your php scripts.
