Find out which class called a method in another class
<p>Is there a way in PHP to find out what object called what method in another object.</p>

<p>Exmaple:</p>

<pre><code>class Foo
{
  public function __construct()
  {
    $bar = new Bar();
    $bar-&gt;test();
  }
}

class Bar
{
  public function test()
  {
  }
}
$foo = new Foo();
</code></pre>

<p>Would there be a way for me to find out that the test method was called from the foo object?</p>
