For my own amusement, I'm writing a function that will print out detailed error messages for an API that I'm creating for a minor project. One of the pieces of information I'd like to return would be the name of the function that called the error function.

I know that I could pass the name of the function as a parameter to the error() function (e.g. error("bad_function","This is dumb")) but I'd rather keep it simpler than that. Is there a way to do this?

    Not without a lower-level stack trace utility like xdebug, as far

huh? what about debug_backtrace() ... contains plenty of info, including function names of everything in the stack. of course something like xdebug can take it to a whole new level.

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.
