Laravel foreach variable loop scope

Question

When I use Laravel blade file foreach loop, the variable is accessible after the foreach loop, whereas the scope of the variable should be only within the loop

@foreach($user->referral as $ref)
  <tr>
    <td>{{ $ref->referral_amount }}</td>
    <td>{{ $ref->status }}</td>
  </tr>
@endforeach

$ref: This variable is accessible outside endforeach loop after @endforeach

No, the only reason that is possible is if you already send a $ref variable to your view from your controller/view-composer/.. — Christophvh

@Christophvh I tried a foreach, and didn't have that variable passed from the controller — Mehravish Temkar

I know it shouldn't be accessible, but I am able to access the variable outside the loop, no idea why @HirenGohel — Mehravish Temkar

From the foreach docs:

Warning

Reference of a $value and the last array element remain even after the foreach loop. It is recommended to destroy it by unset()

So, if you want to destroy the reference, do this:

<?php unset($ref); ?>

Or:

@php unset($ref); @endphp

As per your problem you can use unset() method of php for destroy a variables.

For that you can use this type of code inside your blade file after foreach loop.

<?php
// destroy a single variable
unset($foo);

// destroy a single element of an array
unset($bar['quux']);

// destroy more than one variable
unset($foo1, $foo2, $foo3);
?>

or

@php
// destroy a single variable
unset($foo);

// destroy a single element of an array
unset($bar['quux']);

// destroy more than one variable
unset($foo1, $foo2, $foo3);
@endphp
