你好！我简直无法理解为什么这个登录页面不起作用。我之前使用 php 5.4 在共享服务器上运行过它。我将站点转移到我自己的服务器上，运行 Ubuntu 12.04、apache 2.4.6、php 5.5。

我只是在下面显示整个登录文件，globals.php 包含 mysql 连接，它可以工作。

如果我遗漏了任何信息，请告诉我。

只需通过在 if 语句中测试 print 语句，我认为它在 if （准备）之后失败了。

问题是，在您尝试登录后，它会在 if 语句之后显示一个空白页面。

再次感谢您提前提供的所有帮助，如果我没有提供足够的信息，请告诉我。

我不知何故有一种感觉，它与 mysqli 连接 vs mysql vs PDO 有关？

    <?php 
include( "globals.php" );

尝试改变这个

 $stmt->bind_param('ss', $user, $pass);
$stmt->execute();
$res = $stmt->get_result();
$row = $res->fetch_assoc();
if ($res->num_rows==1)
{
 $_SESSION['username'] = $user; 
$_SESSION['userid'] = $row['id'];
$_SESSION['type'] = 1;
$_SESSION['LAST_ACTIVITY'] = time();
print "<script>alert('You are logged in! Check the menu \"Admin\" section for more information!');</script>";
}

至

 $stmt->bind_param('ss', $user, $pass);
 $stmt->store_result();
 $stmt->execute();

if ($stmt->num_rows==1)
{
$stmt->bind_result($id, $username, $password);
$stmt->fetch();
print "<script>alert('You are logged in! Check the menu \"Admin\" section for more information!');</script>";
}
