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


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.

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:
    [0] => apple
    [1] => raspberry
    [2] => orange
    [3] => banana
