PHP Function rsort()

Syntax

rsort( $array [, $sort_flags] );

Definition and Usage

This function sorts an array in reverse order (highest to lowest).

This function assigns new keys for the elements in array. It will remove any existing keys you may have assigned, rather than just reordering the keys.

Paramters

Parameter	Description
array	Required. Specifies an array.
sort_flags	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

Return Value

Returns TRUE on success or FALSE on failure.

Example

Try out following example:

<?php
$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana" );
rsort($fruits);
print_r($fruits);
?>

This will produce following result:

Array ( [0] => orange [1] => lemon [2] => banana )
