declaring simple variables in views in Laravel

Question

This is probably a simple thing, but I don't know how to declare and increment an integer variable in a view in Laravel.

I have a couple foreach loops that I am using:

@foreach($fans as $fan)     @foreach ($array as $x)          @if($fan->fbid==$x)           @endif     @endforeach   @endforeach 

I would like to throw in an integer variable $a, that counts the number of times it makes it through the if statement. Like:

$a=0; @foreach($fans as $fan)         @foreach ($array as $x)              @if($fan->fbid==$x)              $a++;                                @endif         @endforeach   @endforeach  {{$a}} 

What is the proper syntax for doing this in a view in Laravel? Thank you.

The Blade {{ }} will echo out what you are doing.

You should do it like this:

<?php $a = 0; ?> @foreach($fans as $fan)         @foreach ($array as $x)              @if ($fan->fbid == $x)                  <?php $a++; ?>                                @endif         @endforeach @endforeach  {{$a}}
