什麼是錯的，上面的代碼？它不斷給我

'Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/u599980382/public_html/newsite/index.php:1) in /home/u599980382/public_html/newsite/connect.php on line 2'.

它不具有幾乎相同的確切的代碼做任何其他的網頁，甚至沒有一個頁面（只有內容是不同的）;它只在索引上做到這一點。預先感謝您提供的任何幫助。

最有可能的東西' session_start（）'正在向瀏覽器發送輸出。如果你爲你的腳本提供代碼，這主要是'session_start（）'代碼和之前的任何代碼。 – PhearOfRayne

你的代碼沒問題。這可能是connect.php或header.php的錯誤。我認爲你的這段代碼是可以的。我嘗試使用我的頁眉，頁腳和連接文件的代碼。那麼它的工作。 :) – Nytram

這可能是'session_start（）'之前的任何輸出引起的，即使在你的php標籤之前有一個空格 - ' - ><？php ...'。 – Sean

使用的頭功能頭尚未發出您可以通過 headers_sent

// If no headers are sent, send one 
if (!headers_sent()) { 
...... 
}

檢查它，你可以更改您的代碼這種情況下：之前

<?php 
include 'header.php'; 
include 'connect.php'; 
include 'content.php'; 
?>
