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

This function does the job without debug_backtrace :

/*
usage :
some code...
getRealCallClass(__FUNCTION__);
some code...
*/

function getRealCallClass($functionName) //Parameter value must always be __FUNCTION__
{
  try
   {
     throw new exception();
   }
  catch(exception $e)
   {
     $trace = $e->getTrace();
     $bInfunction = false;
     foreach($trace as $trace_piece)
      {
          if ($trace_piece['function'] == $functionName)
           {
             if (!$bInfunction)
              $bInfunction = true;
           }
          elseif($bInfunction) //found !!!
           {
             return $trace_piece['class'];
           }
      }
   }
}
