将标题放在while循环之外，可以得到一张桌子，如下所示：
<?php
session_start();
include_once 'admin_navmenu.php';
$premium = 1;
$sql = "SELECT * FROM users WHERE premium = ?;";
$stmt = mysqli_stmt_init($conn);
if (!mysqli_stmt_prepare($stmt, $sql)) {
echo 'SQL error';
} else {
mysqli_stmt_bind_param($stmt, "i", $premium);
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
$resultCheck = mysqli_num_rows($result);
if ($resultCheck < 1) {
echo 'There are no premium users!';
}
echo '<table class="user_information_premium">
<tr>
<th colspan="2" class="update_title">General Information: Premium Membership Users
</tr>';
while($row = mysqli_fetch_assoc($result)) {
if ($row['admin'] == 0) {
$admin = 'No';
} else {
$admin = 'Yes';
}
if ($row['moderator'] == 0) {
$moderator = 'No';
} else {
$moderator = 'Yes';
}
if ($row['user_activate'] == 0) {
$activate = 'No';
} else {
$activate = 'Yes';
}
if ($row['premium'] == 0) {
$premium = 'No';
} else {
$premium = 'Yes';
}
echo '
<tr>
<th>User ID:</th><td>',htmlspecialchars($row['user_id']),'</td>
</tr>
<tr>
<th>First Name:</th><td>',htmlspecialchars($row['user_first']),'</td>
</tr>
<tr>
<th>Last Name</th><td>',htmlspecialchars($row['user_last']),'</td>
</tr>
<tr>
<th>Email Address:</th><td>',htmlspecialchars($row['user_email']),'</td>
</tr>
<tr>
<th>User ID:</th><td>',htmlspecialchars($row['user_uid']),'</td>
</tr>
<tr>
<th>Country Status:</th><td>',htmlspecialchars($row['user_country']),'</td>
</tr>
<tr>
<th>Admin Status:</th><td>',htmlspecialchars($admin),'</td>
</tr>
<tr>
<th>Moderator Status:</th><td>',htmlspecialchars($moderator),'</td>
</tr>
<tr>
<th>Free Lesson Status:</th><td>',htmlspecialchars($row['freelesson']),'</td>
</tr>
<tr>
<th>Date Joined Status:</th><td>',htmlspecialchars($row['datejoined']),'</td>
</tr>
<tr>
<th>User Session Status(Last Login):</th><td>',htmlspecialchars($row['user_session']),'</td>
</tr>
<tr>
<th>Activate Non Premium Status:</th><td>',htmlspecialchars($activate),'</td>
</tr>
<tr>
<th>Premium Status:</th><td>',htmlspecialchars($premium),'</td>
</tr>';
}
echo '</table>';
}
但是如何在while循环外仍然有3个标题的同时做3个单独的表？另外，使用'，'和'..'有什么区别？当您具有href标记之类的链接时，是否会使用“ ..”？对于上面的代码，我一直在将'，'与htmlspecialchars一起使用，这是正确的格式吗？
我尝试了以下更新的代码，并认为它应该可以工作，但是看起来很奇怪，如下图所示：
