PHP: initialize array using array_fill()

Using the function array_fill() you can easily initialize your array with a defined value. For example you need an array $array which will have 10 fields and each field will contain 'x'. Using the array_fill() the task will be simple.

$array = array_fill(0, 10, 'x');
print_r($array);


Here the second parameter of the function is the number of fields of the array after the provided index. It must be a positive integer. If you put number of fields is 0, means the second parameter. You'll get the below error.

Warning: array_fill(): Number of elements must be positive in E:\temp\temp.php on line 3

For the above code, the output will be,

Array
(
    [0] => x
    [1] => x
    [2] => x
    [3] => x
    [4] => x
    [5] => x
    [6] => x
    [7] => x
    [8] => x
    [9] => x
)
