PHP implementation of Bozo sort

Tue, 01/16/2007 - 22:48 | by Mgccl

Bozo Sort is more efficient than than bogosort(in theory). It does sorting by randomly chose 2 items and compare them, then switch them if needed. Until everything is sorted.

function bozo_sort($array){
	$sorted = $array;
	sort($sorted);
	while($sorted !== $array){
		$i = array_rand($array);
		$j = array_rand($array);
		if($i < $j){
			if($array[$i] > $array[$j]){
				$z = $array[$j];
				$array[$j] = $array[$i];
				$array[$i] = $z;
			}
		}else{
			if($array[$j] > $array[$i]){
				$z = $array[$i];
				$array[$i] = $array[$j];
				$array[$j] = $z;
			}
		}
	}
	return $array;
}
