Laravel - assign js variable php value

Question

How do i assign a js variable a php value, for example i have this js variable called nr and a php var $nr.

@php
    $gal = \App\Gallery::where('id',$wid[1])->first();
    $p = json_decode($gal->photo,true);
    $nr = count($p);
@endphp

 <script>
    var nr={PHP variable here};</script>

Not a big fan of using @php ... @endphp in a view file, I'd declare it in the Controller, assign it to the view and use <script>var nr={{$myVar}}</script> in the view file — user8034901

Try this var nr= {{!! $nr !!}};
You can change your code a bit and achieve the same result by doing this:

@php
    $gal = \App\Gallery::where('id',$wid[1])->first()->photo;
@endphp

<script>
    var gal = @json($gal)
    var nr = gal.length
</script>
