ksort

Description

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

Returns TRUE on success or FALSE on failure.

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

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