Syntax: array array_pad (array input, int pad_size, mixed pad_value);

Description:

This function fills array arrays with arrays of size pad_size and value pad_value, and returns the padded array, if the argument pad_size is a positive number, padding to the right of the array and, if negative, padding to the left of the array. If the absolute value of the parameter pad_size is less than or equal to the length of the array input, it will not be padded.

Example:

<?php

$input = Array (12, 10, 9);

$result = Array_pad ($input, 5, 0);

Result is Array (12, 10, 9, 0, 0)

$result = Array_pad ($input,-7,-1);

Result is array (-1,-1,-1,-1, 12, 10, 9)

$result = Array_pad ($input, 2, "NoOp");

Not padded
