How to use array_pad() Function In PHP

Using array_map() and range() Functions

The array_pad() function can pad an array to a specified length with a specified value, starting from an initial empty array.

<?php
function zeroFilledArr($len) {
    return array_pad([], $len, 0);
}
// Driver code
$len = 5;
$arr = zeroFilledArr($len);
print_r($arr);
?>

Array
(
    [0] => 0
    [1] => 0
    [2] => 0
    [3] => 0
    [4] => 0
)
