// Sometimes it's necessary to retrieve the value of $this from within an object.
// This solution dedicates a public var $ID to store a unique identifier for the object:
class Someclass {
public $ID;
public function what_is_this() {
return '$this is: ' . $this->get_varname();
}
private function get_varname() {
$this->ID = uniqid();
foreach($GLOBALS as $key => $val) {
if (is_a($val,'Someclass')) {
if ($val->ID === $this->ID) {
return $key;
break;
}
}
}
}
}
// example:
$my_var_instance = new Someclass;
echo $my_var_instance->what_is_this(); // returns '$this is: my_var_instance'
