PHP array_fill() function

array_fill($start_index, $number_elements, $values)

1. $start_index: This parameter specifies the starting position of filling up the values into the array, the user wants to create. If $start_index is negative, the first index of the returned array will be $start_index and the following indices will start from zero. So it is better to assign a positive value to it. This is a mandatory parameter and must be supplied.
2. $number_elements: This parameter refers to the number of elements, the user wants to enter into the array. The $number_elements should be positive (including 0, for ver 5.6.0) otherwise E_WARNING is thrown. This is also a mandatory parameter.
3. $values : This parameter refers to the values we want to insert into the array. These values can be of any type.

Input : $start_index = 2; $number_elements = 3;
        $values = "Geeks";
Output :
        Array
        (
          [2] => Geeks
          [3] => Geeks
          [4] => Geeks
        )

Input : $start_index = -10; $number_elements = 3;
        $values = 45;
Output :
        Array
        (
          [-10] => 45
          [0] => 45
          [1] => 45
        )

<?php

// PHP code to illustrate the working of array_fill()

function Fill($start_index, $number_elements, $values){
    return(array_fill($start_index, $number_elements, $values));
}

// Driver Code
$start_index = 2;
$number_elements = 5;
$values = "Geeks";
print_r(Fill($start_index, $number_elements, $values));
?>

Array
(
    [2] => Geeks
    [3] => Geeks
    [4] => Geeks
    [5] => Geeks
    [6] => Geeks
)
