php解决约瑟夫环的问题

php里面解决约瑟夫环还是比较方面的，但是下面的方法太费空间

<?php

class SelectKing{

	private $m;//幅度

	private $n;//总数

	public function __construct($m,$n){

		$this->m = $m;

		$this->n = $n;

	}

	public function getKing(){

		$mokeys = range(1, $this->n);

		$tmp = 0;

		while(count($mokeys)>1){

			$tmp++;

			$head = array_shift($mokeys);

			if($tmp%$this->m!=0){

				array_push($mokeys, $head);

			}

		}

		return $mokeys;

	}

}

class Client{

	public static function main(){

		$obj = new SelectKing(3, 10);

		$king = $obj->getKing();

		var_dump($king);

	}

}

Client::main();

?>
