Complete PHP Array Reference

## Definition and Usage

The array_pad() function inserts a specified number of elements, with a specified value, to an array.

## Syntax

    array_pad(array,size,value)

Parameter | Description
--- | ---
array | Required. Specifies an array
size | Required. Specifies the number of elements in the array returned from the function
value | Required. Specifies the value of the new elements in the array returned from the function

## Tips and Notes

Tip: If you assign a negative size parameter, the function will insert new elements BEFORE the original elements. (See example 2)

Note: This function will not delete any elements if the size parameter is less than the original array's size.

## Example 1

    <?php
    $a=array("Dog","Cat");
    print_r(array_pad($a,5,0));
    ?>

The output of the code above will be:

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

## Example 2

With a negative size parameter:

    <?php
    $a=array("Dog","Cat");
    print_r(array_pad($a,-5,0));
    ?>

The output of the code above will be:

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