mysql_fetch_array 与 mysql_fetch_object函数与用法

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
