How to use array_map() and range() Functions In PHP

The combination of array_map() and range() can create a zero-filled array.

range(1, $length) generates an array of integers from 1 to $length.
array_map() applies a callback function that returns 0 for each element in the range array, resulting in a zero-filled array.

Example: This example shows the use of array_map() and range() function to create zero filled array.

PHP

<?php
function zeroFilledArr($len) {
    return array_map(function() { 
        return 0; 
    }, range(1, $len));
}
// Driver code
$len = 5;
$arr = zeroFilledArr($len);
print_r($arr);
?>

Output

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