Php Solutions
Solution 1 - Php
Replace var_dump() with the debug method dump() provided by Doctrine Common.
\Doctrine\Common\Util\Debug::dump($user);
It works for single objects and Doctrine collections and should prevent browser displaying issues you are having.
Solution 2 - Php
well formatted :
echo '<pre>';
\Doctrine\Common\Util\Debug::dump($user, $recurciveLevelToDisplay);
echo '</pre>';
Solution 3 - Php
Simple and easy example.
var_dump(serialize($Object));
Solution 4 - Php
Symfony < 2.6
You can use \Doctrine\Common\Util\Debug::dump($variable, $depth); it displays doctrine output without the proxy information.
Symfony > 2.6
If you are using symfony 2.6 or more, I strongly advice you to use dump().
It shows a well formated and colored output, and you can dynamically expend/hide rows.
Solution 5 - Php
The problem is that in a bidirectional relationship both entities have a link to each other, so while displaying entity1 var_dump will also have to print all properties of entity2, which include entity1 itself giving you a loop.
Solution 6 - Php
The get_object_vars() improve the visualization too.
echo "<pre>";
\Doctrine\Common\Util\Debug::dump(get_object_vars($user));
Solution 7 - Php
With Symfony 2.6 you can now just use dump($var) in your controller and {{ dump(var) }} in twig.
Make sure to add this to your AppKernal.php file, in the array('dev', 'test') section.
$bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();

use dump($user) and you can see perfect result in Symfony Profiler! good luck
Solution 9 - Php
Just use echo serialize($user);
