krsort -- Sort an array by key in reverse order


bool krsort ( array &array [, int sort_flags] )

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

$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
foreach ($fruits as $key => $val) {
    echo "$key = $val\n";

The above example will output:

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().

See also asort(), arsort(), ksort(), sort(), natsort(), and rsort().
