Description
int ksort (array array [, int sort_flags])
Sorts an array by key, maintaining key to data correlations. This is useful mainly for associative arrays.
Example 1. Ksort() example
$fruits = array ("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple"); ksort ($fruits); reset ($fruits); while (list ($key, $val) = each ($fruits)) { echo "$key -> $val\n"; } |
|
This example would display:
You may modify the behavior of the sort using the optional parameter sort_flags, for details see sort().
See also asort(), arsort(), sort(), natsort(), and rsort().
Note: The second parameter was added in PHP 4.
