rsort -- Sort an array in reverse order


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

This function sorts an array in reverse order (highest to lowest).

Note: This function assigns new keys for the elements in array. It will remove any existing keys you may have assigned, rather than just reordering the keys.

Returns TRUE on success or FALSE on failure.

Example 1. rsort() example

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

The above example will output:

0 = orange
1 = lemon
2 = banana
3 = apple

The fruits have been sorted in reverse alphabetical order.

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

See also arsort(), asort(), ksort(), krsort(), sort(), and usort().
