所引用的封装类

<?phpclass DBDA{ public $host = "localhost"; public $uid = "root"; public $pwd = "123"; public $dbname = "test_123"; //执行SQL语句返回相应的结果 //$sql 要执行的SQL语句 //$type 代表SQL语句的类型，0代表增删改，1代表查询 function query($sql,$type=1) { $db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname); $result = $db->query($sql); if($type) { //如果是查询，显示数据 return $result->fetch_all(); } else { //如果是增删改，返回true或者false return $result; } }}
