In Perl (and some other languages) you can call some methods in both object and class (aka static)
context. I made such a method for one of my classes in PHP5, but found out that static methods in
PHP5 do not 'know' the name of the calling subclass', so I use a backtrace to
determine it. I don't like hacks like this, but as long as PHP doesn't have an
alternative, this is what has to be done:
public function table_name() {
$result = null;
if (isset($this)) { // object context
$result = get_class($this);
}
else { // class context
$result = get_class();
$trace = debug_backtrace();
foreach ($trace as &$frame) {
if (!isset($frame['class'])) {
break;
}
if ($frame['class'] != $result) {
if (!is_subclass_of($frame['class'], $result)) {
break;
}
$result = $frame['class'];
}
}
}
return $result;
}
