如果用户未登录，并且他们是用户的个人资料，收件箱和帐户选项，我将使用登录/注册选项创建标题。我在头部顶部使用<?php include_once "../scripts/checkuserlog.php"; ?>，在div中使用<?php echo $logOptions; ?>我希望单词显示出来。我得到的错误是“warning：session_start（）[function.session-start]：无法发送会话缓存限制器 - 已经发送的头文件（输出在/home/ssdotcom/public_html/index.php:6开始）在第2行的“/home/ssdotcom/scripts/checkuserlog.php”这对我来说很啰嗦，第二行是一个打开的div标签。 ..这里是头文件中的代码：检查用户日志问题
<?php include_once "../scripts/checkuserlog.php"; ?>
<div id="header">

与头部标签的上方，其余当然。 – Nathan
必须在脚本输出任何内容之前调用session_start（）。即使你有'echo'“;'某处，那么cookie头文件也不能被发送。将'include_once（... checkuserlog.php）'移到index.php的顶部。看看是否有效。 – arunkumar
