array_reverse

(PHP 4, PHP 5)

array_reverse -- Return an array with elements in reverse order

Description

array array_reverse ( array array [, bool preserve_keys])

array_reverse takes input array and returns a new array with the order of the elements reversed, preserving the keys if preserve_keys is TRUE.

Example 1. array_reverse() example

<?php

$input  = array("php", 4.0, array("green", "red"));

$result = array_reverse($input);

$result_keyed = array_reverse($input, true);

?>

This makes both $result and $result_keyed have the same elements, but note the difference between the keys. The printout of $result and $result_keyed will be:

Array

(


  [0] => Array

    (

      [0] => green

      [1] => red

    )



  [1] => 4

  [2] => php

)

Array

(

  [2] => Array

    (

      [0] => green

      [1] => red

    )



  [1] => 4

  [0] => php

)

Note: The second parameter was added in PHP 4.0.3.
