Laravel Collection won't pull a value

I have a Laravel Collection that I am pushing a value to e.g. 'orange'. When I test for a value and attempt to pull a value, the collection remains the same.

$collection = collect(['red', 'green', 'blue']);

$collection->push('orange');
    
if($collection->contains('green')) {

    logger('Got green!');
        
    $collection->pull('green');
 }

I'm sure I am missing something trial but why is green not removed from the final collection?

because pull method remove item by its key not value ,so you need to get the item key ( index ) first so that you can pass it to pull or forget method to remove it .

you can do like this :-

$collection = collect(['red', 'green', 'blue']);

$collection->push('orange');
    
if($collection->contains('green')) {

    logger('Got green!');
          $index = $collection->search('green');

    $collection->pull($index);
    // $collection->forget($index);

 }

Well, actually simple non-associative array in php still associative, but its keys are indexes and you can imagine your array as

[0 => 'red', 1 => 'green', 2 => 'blue', 3 => 'orange']

Pull method pulls the item from array by its key. So if you expect to orange item being pulled you should call the method with that item's index:

$collection>pull(3);
