Doctrine Debug dump usage instead of var_dump

DoctrineDebugDump.php

<?php
/**
  * Lazy load proxies always contain an instance of Doctrine’s EntityManager and all its dependencies.
  * Therefore a var_dump() will possibly dump a very large recursive structure which is impossible to render and read.
  * You have to use Doctrine\Common\Util\Debug::dump() to restrict the dumping to a human readable level.
  * Additionally you should be aware that dumping the EntityManager to a Browser may take several minutes,
  * and the Debug::dump() method just ignores any occurrences of it in Proxy instances.
  */

#var_dump($entity); // will possibly dump a very large recursive structure which is impossible to render and read
Doctrine\Common\Util\Debug::dump($entity); // restrict the dumping to a human readable level
?>
