总结:mysql_fetch_object 把记录作来一个对象来处理,像我们用类时就要用->访问,mysql_fetch_array 把记录保存到一个数据所以可以用$rs['下标名'] 或$rs[0]数组编号.
PHP实例代码如下:
$conn=mysql_connect("127.0.0.1","root","root"); mysql_select_db("ip"); $sql="select * from adminblog "; $result=mysql_query($sql,$conn); while($rs=mysql_fetch_array($result)) { echo $rs->username; echo $rs->password; } //运行代码提示Notice: Trying to get property of non-object 好了,我们现在修改一下 while($rs=mysql_fetch_array($result)) { echo $rs['username']; echo $rs['password']; } //输出结果: adsense 5498bef14143cd98627fb0560cb5ded6 //现在来看一个mysql_fetch_object的实例 while($rs=mysql_fetch_object($result)) { echo $rs['username']; } //运行后出来 Fatal error: Cannot use object of type stdClass as array in 说这不是一个数组 while($rs=mysql_fetch_object($result)) { echo $rs->username; //开源代码phprm.com } //输出结果为 adsense
