array_unshift --  Push one or more elements onto 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

$queue = array ("p1", "p3");
array_unshift ($queue, "p4", "p5", "p6");

This would result in $queue having 5 elements: "p4", "p5", "p6", "p1", and "p3".
