今天在測試PHP時
源碼
- <?php
- $RPage = $_GET['RPage'];
- $RID = $_COOKIE["RID"];
- if (!isset($_COOKIE['RID'])){
- setcookie('RID',addslashes($_GET['RID']),time()+2*60*60);
- }
-
- $Click_ID = $_COOKIE['Click_ID'];
- if (!isset($_COOKIE['Click_ID'])){
- setcookie('Click_ID',addslashes($_GET['Click_ID']),time()+2*60*60);
- }
- $RPath = $_SERVER['HTTP_HOST']."/".$RPage;
- if($RPage)
- header("Location: ".$RPath);
- else
- header("Location: ".$_SERVER['HTTP_HOST']);
- ?>
複製代碼
結果輸出
- cannot modify header information - headers already sent by setcookie
複製代碼 可是這頁面根本沒輸出阿
怎麼會這樣
請教古歌大神
I also encountered this exact problem and finally found a solution. You have to save the file without the utf-8 BOM signature since that includes a character at the top of the document. In adobe dreamviewer I just had to uncheck the "Include Unicode Signature (BOM)" when saving the file and my problem was solved. 您必須保存沒有utf-8 BOM簽名的文件,因為在文檔頂部包含一個字符。
在Adobe DreamWaver中,在保存文件時取消選中“包括Unicode簽名(BOM)”,問題就解決了。
