rsortSort an array in reverse order


bool rsort ( array &$array [, int $sort_flags= SORT_REGULAR ] )

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



The input array.


You may modify the behavior of the sort using the optional parameter sort_flags , for details see sort().

Return Values

Returns TRUE on success or FALSE on failure.


Example #1 rsort() example

= array("lemon""orange""banana""apple");
foreach (
$fruits as $key => $val) {
"$key = $val\n";

The above example will output:

0 = orange
1 = lemon
2 = banana
3 = apple

The fruits have been sorted in reverse alphabetical order.


Note: This function assigns new keys to the elements in array . It will remove any existing keys that may have been assigned, rather than just reordering the keys.
