一个很奇怪的问题:同样的一条sql语句,在mysql中能查到记录,而在php中却查不到
具体如下:
mysql中数据表结构:


sql语句:
SELECT ID FROM tradeDetails WHERE userName = '李四' AND goodsID ='1'

php代码:

<?php<br />mysql_connect("localhost","root","root");<br />mysql_query("set names utf-8");<br />mysql_select_db("test");<br /><br />// 为方便说明问题,我把条件参数设为常量<br />$querySql="SELECT ID FROM tradeDetails WHERE userName = '李四' AND goodsID ='1'"; <br /><br />$rs=mysql_query($querySql);<br />$totalRows_myrs=mysql_num_rows($rs); <br />echo $totalRows_myrs;<br />?>
Copy after login


我将sql语句放到mysql中执行能查到1条记录,而php页面执行时,却不能查到记录。求解。
------解决方案--------------------
mysql_query("set names utf8");
------解决方案--------------------
php文件的本身也要是utf8编码。
