PHP rsort

Definition and Usage

The rsort() function sorts an array by the values in reverse order. This function assigns new keys for the elements in the array. Existing keys will be removed. This function returns TRUE on success, or FALSE on failure.

Syntax

rsort(array,sorttype)

array : Required. Specifies the array to sort

sorttype : Optional. Specifies how to sort the array values. Possible values:

* SORT_REGULAR - Default. Treat values as they are (don't change types)
* SORT_NUMERIC - Treat values numerically
* SORT_STRING - Treat values as strings
* SORT_LOCALE_STRING - Treat values as strings, based on local settings


<?php
$my_array = array("a" => "Hamburger", "b" => "Cheese", "c" => "Jam");

rsort($my_array);
print_r($my_array);
?>


The output of the code above will be:

Array
(
[0] => Jam
[1] => Hamburger
[2] => Cheese
)
