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.
[snip!]
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.
