Not without a lower-level stack trace utility like xdebug, as far as I know. However, you can slightly modify your code to do this: <?php function error ($func,$message) { print "The error message is $message"; print "The function that called the error was: ".$func."\n"; } function bad_function($param) { error (__FUNCTION__,"This is dumb"); return false; } bad_function("blah"); ?> I also placed that online in my code library (to which I always forget to link, but have dozens of examples), along with a function to list all of the user-level functions available to the current script.
