Inject a string with quotes from PHP to javascript

Question

I'm facing a problem when trying to inject a string from PHP (using the Laravel framework) into javascript.

The string is like [{"foo1": bar1}, {"foo2" : bar2}]. When I inject this string to javascript using something like var test = '{{ $var }}' the " are converted to ". The javascript string is used in a function later to parse the JSON. This now fails because of the quote-conversion.

It seems that the string is passed into the browser as it should be. But Chrome converts it.

How can I solve this? I've tried PHP's str_replace(), html_entity_decode(), json_encode() and Javascript's replace(). Both aren't solving the issue.

You shouldn't get the behaviour you describe unless you have something transforming the variable before it gets inserted. The {{ }} syntax suggests some kind of template engine. You'll need to provide more information about what that is. — Quentin

I think you are using blade template in laravel. Could you please try

{ $var } instead of {{ $var }}

Awesome! Since I'm using Laravel5 it had to be {!! $var !!}. Thanks, +1 and accepted. Have a nice day :)
