RE: [PHP] Simple error handling... but how? - Register your own error-handler with PHP

You can register your own error-handler using the function: set_error_handler(<error_handler_function_name>); Your customised error_handler will then get called whenever an error gets called. Your function is passed the follwing parameters: function error_handler_function_name($errno, $errstr, $errfile, $errline) This is nice as it passes you the file and line number as well as the error number and the error string. You can then use this for sending your own informational debug messages to the error handler by using the trigger_error() routine. The handler that I use dumps everything to a debug file - using error_log(). This is great as I get all of my parsing errors and informational debug messages sent to the same place. By sending them to a file (rather than the screen) you stop headers being sent, which in turn could cause you problems. I believe that this functionality only became available in 4.02. You may also want to check out the assert() functions. These are similar and are great for putting sanity checks into your code. I think that the assert handler code was the inspiration for the error handling code.

This might have been widely discussed already, but I haven't been able to find useful information about it: How can I present a customized error page whenever a PHP error or warning ocurrs?
