如果用戶未登錄，並且他們是用戶的個人資料，收件箱和帳戶選項，我將使用登錄/註冊選項創建標題。我在頭部頂部使用<?php include_once "../scripts/checkuserlog.php"; ?>，在div中使用<?php echo $logOptions; ?>我希望單詞顯示出來。我得到的錯誤是「warning：session_start（）[function.session-start]：無法發送會話緩存限制器 - 已經發送的頭文件（輸出在/home/ssdotcom/public_html/index.php:6開始）在第2行的「/home/ssdotcom/scripts/checkuserlog.php」這對我來說很囉嗦，第二行是一個打開的div標籤。 ..這裏是頭文件中的代碼：檢查用戶日誌問題
<?php include_once "../scripts/checkuserlog.php"; ?>

與頭部標籤的上方，其餘當然。 – Nathan
必須在腳本輸出任何內容之前調用session_start（）。即使你有'echo'「;'某處，那麼cookie頭文件也不能被髮送。將'include_once（... checkuserlog.php）'移到index.php的頂部。看看是否有效。 – arunkumar
