            $image_path = public_path($path);
                if (file_exists($image_path)) {
                        File::delete($image_path);

                }

how can i achieve that in Laravel? thanks

If you convert your images array to a collection, you can use the either the filter or reject methods to remove the desired element.

Using reject:

$images = [
    "f3bd5ad57c8389a8a1a541a76be463bf.png",
    "37aa5dfc44dddd0d19d4311e2c7a0240.jpg",
    "e287f0b2e730059c55d97fa92649f4f2.jpg"
    ];

$imagesToRemove = ['f3bd5ad57c8389a8a1a541a76be463bf.png'];

$collection = collect($images)->reject(function ($value) use ($imagesToRemove) {
    return in_array($value, $imagesToRemove);
});

dd($collection);

Using filter:

$images = [
    "f3bd5ad57c8389a8a1a541a76be463bf.png",
    "37aa5dfc44dddd0d19d4311e2c7a0240.jpg",
    "e287f0b2e730059c55d97fa92649f4f2.jpg"
    ];

$imagesToRemove = ['f3bd5ad57c8389a8a1a541a76be463bf.png'];

$collection = collect($images)->filter(function ($value) use ($imagesToRemove) {
    return !in_array($value, $imagesToRemove);
});

dd($collection);

Both achieve the same outcome.
