Question

我是php的新手，我想知道如何查看消息

这是我的代码

$idto = $_GET['id'];
$query2 = mysql_query("select * from users where id =".$idto." ");
$row2 = mysql_fetch_assoc($query2);
echo "<b><font size='6' face='Comic Sans MS'><center>".$row2['firstname']."</center></font></b><br><br>";


$query2 = mysql_query("select * from message  where id_from =".$idto."  and id_to =". $_SESSION['id']." ORDER BY id");
$query1 = mysql_query("select * from message  where id_to =".$idto."  and id_from =". $_SESSION['id']." ORDER BY id");

我选择user1＆amp;发送的消息用户2，但我不知道如何正确查看它们当我使用这个

while ($row = mysql_fetch_assoc($query2) ) 
{


echo'<fieldset style="width:250" align="center">';
echo"<legend><b>".$row2['firstname']."</b></legend>";
echo $row['message'];
echo "<br>";
echo $row['date'];
echo"<hr>";
echo"</fieldset>";


}



while ($row1 = mysql_fetch_assoc($query1) ) 
{




echo'<fieldset style="width:250" align="center">';
echo"<legend><b>".$_SESSION['firstname']."</b></legend>";
echo $row1['message'];
echo "<br>";
echo $row1['date'];
echo"<hr>";
echo"</fieldset>";




}

它以错误的方式查看邮件请任何人帮助我，谢谢:) 如果你不明白我在说什么我的意思是我想知道如何查看消息

首先从mysql_ *切换到mysqli_ *因为不推荐使用mysql_ *函数。

按升序排序查询：

$query1 = mysql_query("
    SELECT * 
    FROM message 
    WHERE id_to = ".$idto." 
    AND id_from = ".$_SESSION['id']." 
    ORDER BY id ASC
");

$query2 = mysql_query("
    SELECT * 
    FROM message 
    WHERE id_from = ".$idto." 
    AND id_to = ".$_SESSION['id']." 
    ORDER BY id ASC
");

在消息系统中我不知道如何查看消息
