Too much data with var_dump in symfony2 doctrine2

Question

I have about 40 entities and many bi-directional relationships. Whenever I use var_dump ($ user) or any entity, my browser loads too many arrays and variables, then it just crashes.

I want a problem.

Data is inserted in a fine. May I cause a problem in production.

Answer 1

Replace var_dump () with the debug method dump () provided by Doctrine Common.

\Doctrine\Common\Util\Debug::dump($user); 

It works for individual Doctrine objects and collections and should prevent the browser from displaying the problems you have.

Answer 2

well formatted:

 echo '<pre>'; \Doctrine\Common\Util\Debug::dump($user, $recurciveLevelToDisplay); echo '</pre>'; 

Answer 3

A simple and easy example.

 var_dump(serialize($Object)); 

Answer 4

The problem is that in a bidirectional manner, both objects have a reference to each other, so when displaying entity1, var_dump will also have to print all the properties of entity2, which include entity1 itself, which gives you a loop.

Answer 5

The get_object_vars () function improves visualization.

 echo "<pre>"; \Doctrine\Common\Util\Debug::dump(get_object_vars($user)); 

Answer 6

Just use echo serialize ($ user);

Answer 7

use a dump ($ user) and you can see a great result in Symfony Profiler! good luck

Answer 8

Symfony <2.6

You can use \Doctrine\Common\Util\Debug::dump($variable, $depth); , which displays the conclusion of the doctrine without proxy information.

Symfony> 2.6

If you are using symfony 2.6 or more, I highly recommend that you use dump() . It shows a well-formed and colored output, and you can dynamically spend / hide lines.

Answer 9

With Symfony 2.6, now you can simply use dump ($ var) in your controller and {{dump (var)}} in the branch.

Be sure to add this to your AppKernal.php file in the array section ('dev', 'test').

 $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
