Example #1
rsort(3) example
<?php
$fruits = array("lemon", "orange", "banana", "apple");
rsort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val
";
}
?>
The above example will output:
0 = orange
1 = lemon
2 = banana

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.
