Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.
<?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 = orangeYou may modify the behavior of the sort using the optional parameter sort_flags, for details see sort().
