How to use array_fill() Function In PHP
The array_fill() function is a straightforward way to create an array filled with a specified value.
Example: array_fill(0, $length, 0) creates an array starting at index 0, with $length elements, each initialized to 0.
<?php
function zeroFilledArr($len) {
return array_fill(0, $len, 0);
}
// Driver code
$len = 5;
$arr = zeroFilledArr($len);
print_r($arr);
?>
Output
Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 )
