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 <?php
$queue = array("orange", "banana");
array_unshift($queue, "apple", "raspberry");
?> |
This would result in $queue having the
following elements:
Array
(
[0] => apple
[1] => raspberry
[2] => orange
[3] => banana
) |
