Laravel - Collections - Method Pad

The pad method will fill the array with the given value until the array reaches the specified size. This method behaves like the array_pad PHP function.

To pad to the left, you should specify a negative size. No padding will take place if the absolute value of the given size is less than or equal to the length of the array:

    $collection = collect(['A', 'B', 'C']);
    $filtered = $collection->pad(5, 0);
    // ['A', 'B', 'C', 0, 0]
    $filtered = $collection->pad(-5, 0);
    // [0, 0, 'A', 'B', 'C']
