php header()函數

php中header函數用法執行個體總結: 希望對你有協助！
1. 頁面沒找到 Not Found
header('HTTP/1.1 404 Not Found');
2. 用這個header指令來解決URL重寫產生的404 header
header('HTTP/1.1 200 OK');
3. 訪問受限
header('HTTP/1.1 403 Forbidden');
// The page moved permanently should be used for
// all redrictions, because search engines know
// what's going on and can easily update their urls.
4. 頁面被永久刪除，可以告訴搜尋引擎更新它們的urls
header('HTTP/1.1 301 Moved Permanently');
5. 伺服器錯誤
header('HTTP/1.1 500 Internal Server Error');
6. 重新導向到一個新的位置
header('Location: http://www.example.org/');
7. 延遲一段時間後重新導向
header('Refresh: 10; url= http://www.example.org/');
echo 'You will be redirected in 10 seconds';
8. 載入要下載的檔案:
readfile('example.zip');
9. 也可以使用HTML文法來實現延遲
header('Content-Transfer-Encoding: binary');
10. 禁止緩衝當前文檔:
header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
header('Expires: Mon, 26 Jul 2010 05:00:00 GMT');
header('Pragma: no-cache');
11. 顯示登入對話方塊，可以用來進行HTTP認證
header('HTTP/1.1 401 Unauthorized');
header('WWW-Authenticate: Basic realm="Top Secret"');
echo 'Text that will be displayed if the user hits cancel or ';
echo 'enters wrong login data';
12. 設定內容類型:
header('Content-Type: text/html; charset=iso-8859-1');
header('Content-Type: text/html; charset=utf-8');
header('Content-Type: text/plain'); // plain text file
header('Content-Type: image/jpeg'); // JPG picture
header('Content-Type: application/zip'); // ZIP file
