__toString() must not throw an exception.


If you an exception handler even that seems fail (in itself) with __toString() must not throw an exception. There is no nice safe way to handle it. The easiest solution is to catch that error as well. It might seems to be odd, but on the other hand the exception hanler shall not fail ;)

* String representation of this object
* @return string
public function __toString()
try {
return (string) $this->name;
} catch (Exception $exception) {
return '';
