mysql_fetch_array 与 mysql_fetch_object函数与用法

$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'];
  }
