我使用bluehost作为我的webhost,我遇到了一些问题.下面的代码是我的困惑点.
<?php
include '../init.php';
error_reporting(0);
?>

<?php

$_SESSION['user_id'] = $login;
if (isset($_SESSION['user_id'])){
mysql_query("UPDATE `users` SET `online_offline`='1' WHERE `user_id`='$_SESSION[user_id]'");
}
header("Location: http://sound-booth.com/");
exit();
}
}
}
echo output_errors($errors)
?>
</div>
</body>
</html>
是脚本的链接.它适用于localhost,但不适用于我的实际服务器.即使header()重定向也不起作用.
有人可以解释一下吗？
解:
ob_start();
最好的选择就是这样使用.
// Use this line instead of header
echo "<script>location='your_url.com'</script>";
必须在发送任何输出之前设置标头.在进行该header()调用之前,您正在向用户发送大量HTML .也许它在一个环境中工作但在另一个环境中工作,因为它output_buffering是在您的localhost php.ini上设置的,而不是在服务器上.
您应该重新编写代码以确保header()在任何内容之前发送,但如果您希望将其工作添加ob_start()到代码的开头,则会强制执行缓冲.
