krsort

Description

Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.

Example 1. krsort() example <?php $fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple"); krsort($fruits); reset($fruits); while (list($key, $val) = each($fruits)) { echo "$key = $val\n"; } ?> This example would display: d = lemon c = apple b = banana a = orange

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