Find out which class called a method in another class

Question

Is there a way in PHP to find out what object called what method in another object.

Exmaple:

class Foo
{
  public function __construct()
  {
    $bar         


        

Answer 1

Here is one liner solution

list(, $caller) = debug_backtrace(false, 2);

As of PHP7 this won't work based on the docs: http://php.net/manual/en/function.list.php as we cannot have empty properties, here is a small update:

list($childClass, $caller) = debug_backtrace(false, 2);
