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.
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.
