krsort — Sort an array by key in reverse order
Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.
Returns TRUE on success or FALSE on failure.
Example#1 krsort() example
<?php
$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
krsort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val\n";
}
?>
The above example will output:
d = lemon
c = apple
b = banana
a = orange
