Description:

Reproduce code:

  {
    return $username;
  }
}

$user = new User();
$user->username = "Test";
echo $this->user;
printf("Logged in as: %s\n",$this->user);



Expected result:
----------------

Logged in as: Test

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

only echo and print call __toString()

Actually this is a valid feature request and we said that we try to include this functionality in 5.1 once the inherent engine problems are solved.
