ksort

Description

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

Возвращает TRUE в случае успешного завершения, FALSE в случае возникновения ошибки.

Пример 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"; } ?> This example would display: 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().
