<?php $arr=$_POST[ "xx" ]; include ( "../DBDA.class.php" ); $db=new DBDA(); foreach($arr as $v) { $sql = "update diaoyanxuanxiang set numbers = numbers+1 where ids = '{$v}'" ; $db->Query($sql,1);//1代表$sql的类型 } header ( "location:TouPiao.php" ); ?> |

<?php //执行一个sql语句,返回相应的结果 class DBDA { public $host = "localhost" ; //数据库服务器地址 public $uid = "root" ; //数据库用户名 public $password = "" ; //数据库密码 //执行SQL语句的方法 //参数里面:$sql代表要执行的sql语句;$type是sql语句的类型,0代表查询,1代表其他(增删改);$db代表要操作的数据库 function Query( $sql , $type =0, $db = "0710_info" ) { //造连接对象 $dbconnect = new MySQLi( $this ->host, $this ->uid, $this ->password, $db ); //判断连接是否出错 !mysqli_connect_error() or die ( "连接失败!" ); //执行sql语句 $result = $dbconnect ->query( $sql ); //判断SQL语句类型 if ( $type ==0) { //如果是查询语句返回结果集的二维数组 return $result ->fetch_all(); } else { //如果是其他语句,返回true或false return $result ; } } } |
