我该如何操作它只显示所有只有一个消息的消息，而另一个问题是，当用户读取消息时，下面的这部分代码没有显示。您可以在页面底部找到完整的代码。
此代码部分未在用户阅读新消息后显示，但我不会显示：
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" class="notifications">You have no new messages</div>';
完整代码：
$newpm_sql = mysql_query("SELECT * FROM `pm`
WHERE `to` = '". $_SESSION['id'] ."'
ORDER BY `id` DESC") or die(mysql_error());
if (mysql_num_rows($newpm_sql) == 0) {
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" class="notifications">You have no new messages</div>';
} else {
while ( $row = mysql_fetch_array( $newpm_sql )) {
$from_sql = mysql_query("SELECT * FROM `members`
WHERE `id` = '". $newpm_sql['from'] ."'")
or die(mysql_error());
$from = mysql_fetch_array($from_sql);
if ($row['status'] == 0) {
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" notifications">
<b><a href="page.php?name=profile&id='. $row['from'] .'">'. $row['subject'] .'</a></b><br> '. $row['text'] .'
'</div>';
}
}
}

我看到上次错过的错误。
本声明
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" class="notifications">You have no new messages</div>';
正在while循环中运行，因此您应该使用$newpm将这些多次迭代连接到.=，而不仅仅是=
while ( $row = mysql_fetch_array( $newpm_sql )) {
$from_sql = mysql_query("SELECT * FROM `members`
WHERE `id` = '". $newpm_sql['from'] ."'")
or die(mysql_error());
$from = mysql_fetch_array($from_sql);
if ($row['status'] == 0) {
//$newpm = '<div id="notificationTitle">Message</div>
newpm .= '<div id="notificationTitle">Message</div>
<div id="notificationsBody" notifications">
<b>
<a href="page.php?name=profile&id='. $row['from'] .'">'. $row['subject'] .'</a>
</b>
<br> '.
$row['text'] .'
'</div>';
}
}

首先运行：
SELECT * FROM `pm` WHERE `to` = '<your SESSION ID>'
ORDER BY `id` DESC
并查看是否返回了某些内容。
你也可以这样做：
var_dump(mysql_num_rows($newpm_sql));die;
在第一行运行此mysql_query后，看看它是否返回了您期望的内容。
此外，您可以切换到PDO - 您不会后悔，因为您现在使用旧的PHP功能。
