# array_unshift

(PHP 4 )

array_unshift -- Prepend one or more elements to the beginning of array

## Description

int array_unshift ( array array, mixed var [, mixed ...])

array_unshift() prepends passed elements to the front of the `array`. Note that the list of elements is prepended as a whole, so that the prepended elements stay in the same order. All numerical array keys will be modified to start counting from zero while literal keys won't be touched.

Returns the new number of elements in the `array`.

Example 1. array_unshift() example

    $queue = array ("orange", "banana");
    array_unshift ($queue, "apple", "raspberry");

This would result in `$queue` having the following elements:

    Array
    (
        [0] => apple
        [1] => raspberry
        [2] => orange
        [3] => banana
    )
