所以我刚加入Hostgator.com，想知道为什么我总是会收到此错误:

So I just joined Hostgator.com, and was wondering, why do I always get this error:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/kapip/public_html/main/mainpage.php:5) in /home/kapip/public_html/main/mainpage.php on line 7

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/kapip/public_html/main/mainpage.php:5) in /home/kapip/public_html/main/mainpage.php on line 7

这是什么意思?我知道我可能必须编辑php.ini，但是我不确定要更改什么.谁能帮我吗?谢谢！

What does this mean? I know I have to probably edit the php.ini, but I'm not sure what to change. Can anyone help me out? Thank you!

推荐答案

在执行session_start()例如

// whitespace, any mark up or include that displays something <HERE>
// it will give you that error
<?php
session_start();
