奇怪现象,未知问题.麻烦大家看看.数据库查询类query的

//数据库连接<?php//$conn=mssql_connect("localhost","dabaxitong","dabaxitong","daba..") or die("数据库无法远程,请联系管理员!");//mssql_select_db("ouou") or die("做坏事？");header("Content-Type:text/html;charset=utf-8");$mysqli=new mysqli("localhost","da","da","da");//错误返回if(mysqli_connect_errno()){    printf("连接有问题 %s\n",mysqli_connect_error());    exit;}//设置编码if (!$mysqli->set_charset("utf8")) {    printf("字符集utf8加载错误: %s\n", $mysqli->error);} else {    //printf("设置当前字符集: %s\n", $mysqli->character_set_name());}$mysqli->query("set names 'utf8'");//写库$mysqli->query("set character set 'utf8'");//读库//$mysqli->close();

include './xitong/LianJieMySql.php';//查询 if ($row = $mysqli->query("select * from yonghu where MingZi_ShouJi = '$u'and MiMa='$p'"))    {        $r=$row->fetch_array();        print_r($r);    }else    {        echo mysql_error();    }

更奇怪的是.在phpmyadmin里查询

select * from yonghu where mingzishouji = '134213213';
也是0条返回.这个字段是有134213213

如果直接执行 select * from yonghu 
的话,是可以print_t 的.
1但加入  where mingzishouji = '123' 就无法查询了. 该字段是有这123存在.

好了.是我见鬼了.原来是字段里的错误.
