Not exactly what you want, but check the use of __FUNCTION__:
function error ($message, $fn) {
print "The error message is $message";
print "The function that called the error was: $fn";
}
Function bad_function($param) {
error ("This is dumb", __FUNCTION__);
return false;
}
You can get better (and more complex) information using debug_backtrace
http://php.net/debug_backtrace. Probably doing something like:
function error ($message) {
$backtrace = debug_backtrace();
$fn = $backtrace[1]["function"];
print "The error message is $message";
print "The function that called the error was: $fn";
}
Function bad_function($param) {
error ("This is dumb);
return false;
}
