Laravel – print_r in twig view

Posted by: admin November 30, 2017 Leave a comment


I have a “simple” question I would hope, and that is how can I print_r or at least see the contents of all defined variables in a twig file.

I have tried: {{ variable }} (where variable is an array set for the view

$viewData['variable'] = array('1','2','3');

in the controller.

I have also tried: {{ $variable }} That gives an error.

I would just want to know what is available from my array in the twig file.


You could use the built in {{ dump() }} function. See the documentation.

If you use it without any value in the brackets it will dump all variables available.
For dumping only your array you would do it like this:

{{ dump(viewData) }}

With something like xdebug the output looks quite nice and is readable.

array (size=3)
  0 => string '1' (length=1)
  1 => string '2' (length=1)
  2 => string '3' (length=1)

Although the documentation says it’s not available by default it was added in twig 1.5 and should be ready to use by default.

Of course not the same as print_r but with xdebug enabled it outputs nice and readable var_dump information.


The dump function works but requires the debug option enabled in the environment. If you don’t have the ability to set this you can also just loop through the array:

{% for key, item in variable %}
    * {{ key }} - {{ item }}
{% endfor %}


I’m not sure about doing it in Twig but you can use Laravel’s dd helper to dump and die from within the controller.



In Laravel 5.4 in config-> twigbridge.php set environment to 'debug' => config('app.debug', true)
Now twigbridge debug is enabled on Laravel env
