mysqli多条sql语句查询

query("set names 'utf8"); //多条sql语句 $sql = "select id,name from `user`;"; $sql .= "select id,mail from `user`"; echo $sql; if ($mysqli->multi_query($sql)){//multi_query()执行一条或多条sql语句 do{ if ($rs = $mysqli->store_result()){//store_result()方法获取第一条sql语句查询结果 while ($row=$rs->fetch_row()){ var_dump($row); echo "
"; } $rs->Close(); //关闭结果集 if ($mysqli->more_results()){ //判断是否还有更多结果集 echo "
"; } } }while($mysqli->next_result());//next_result()方法获取下一结果集，返回bool值 } $mysqli->close(); //关闭数据库连接 ?>
