### Description

array array_fill ( int `$start_index` , int `$num` , mixed `$value` )

Fills an array with `num` entries of the value of the `value` parameter, keys starting at the `start_index` parameter.

### Parameters

`start_index`

  The first index of the returned array.

  If `start_index` is negative, the first index of the returned array will be `start_index` and the following indices will start from zero (see example).

`num`

  Number of elements to insert. Must be greater than or equal to zero.

`value`

  Value to use for filling

### Return Values

Returns the filled array

### Errors/Exceptions

Throws a `E_WARNING` if `num` is less than zero.

### Changelog

`<?php
$a = array_fill(5, 6, 'banana');
$b = array_fill(-2, 4, 'pear');
print_r($a);

        [7]  => banana
