(PHP 4, PHP 5)
rsort — Sort an array in reverse order
This function sorts an array in reverse order (highest to lowest).
Note: 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.
Returns TRUE on success or FALSE on failure.
Example#1 rsort() example
<?php
$fruits = array("lemon", "orange", "banana", "apple");
rsort($fruits);
foreach ($fruits as $key => $val) {
echo "$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.
You may modify the behavior of the sort using the optional parameter sort_flags , for details see sort().
