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.
