简单易用的php顺序查找和二分查找的类

class search{	// 查找的源数组	private $array = array(1,2,3,5,7,6,4,8);	/**	* 顺序查找法	* @param $val 要查找的值	*/	public function query_search($val){	foreach ($this->array as $k => $v){	if($v == $val){	echo '顺序查找成功!';	exit(0);	}	}	echo '顺序查找失败!';	}	/**	* 二分查找法	* @param $val 要查找的值	*/	public function bin_search($val){	sort($this->array);	$min = 0;	$max = count($this->array);	for ($i = $min; $i < $max; $i++){	$mid = ceil(($min + $max) / 2);	if($val == $this->array[$mid]){	echo '二分查找成功!';	exit(0);	}else if($val < $this->array[$mid]){	$max = $mid;	}else if($val > $this->array[$mid]){	$min = $mid;	}	}	echo '二分查找失败!';	}
