php’s header function

用这个header指令来解决URL重写产生的404 header
# header('HTTP/1.1 200 OK');
#

# // 页面没找到
# header('HTTP/1.1 404 Not Found');
#

# // 访问受限
# 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.
# //页面被永久删除，可以告诉搜索引擎更新它们的urls
# //PS:第一次碰到这个指令，不知道能不能用来把自己的站点从搜索引擎中删除呢？
# header('HTTP/1.1 301 Moved Permanently');
#

# // 服务器错误
# header('HTTP/1.1 500 Internal Server Error');
#

# // 重定向到一个新的位置
# header('Location: http://www.example.org/');
#

# // 延迟一段时间后重定向
# header('Refresh: 10; url=http://www.example.org/');
# print 'You will be redirected in 10 seconds';
#

# // 也可以使用HTML语法来实现延迟
# // http://www.example.org/ />
#

# // 覆盖 X-Powered-By value
# header('X-Powered-By: PHP/4.4.0');
# header('X-Powered-By: Brain/0.6b');
#

# // 内容语言 (en = English)
# header('Content-language: en');
#

# // 最后修改时间(在缓存的时候可以用到)
# $time = time() - 60; // or filemtime($fn), etc
# header('Last-Modified: '.gmdate('D, d M Y H:i:s', $time).' GMT');
#

# // 告诉浏览器要获取的内容还没有更新
# header('HTTP/1.1 304 Not Modified');
#

# // 设置内容的长度 (缓存的时候可以用到):
# header('Content-Length: 1234');
#

# // 用来下载文件:
# header('Content-Type: application/octet-stream');
# header('Content-Disposition: attachment; filename="example.zip"');
# header('Content-Transfer-Encoding: binary');
# // 加载要下载的文件:
# readfile('example.zip');
#

# // 禁止缓存当前文档:
# header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
# header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
# header('Pragma: no-cache');
#

# // 设置内容类型:
# 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
# header('Content-Type: application/pdf'); // PDF file
# header('Content-Type: audio/mpeg'); // Audio MPEG (MP3,...) file
# header('Content-Type: application/x-shockwave-flash'); // Flash animation
#

# // 显示登录对话框，可以用来进行HTTP认证
# header('HTTP/1.1 401 Unauthorized');
# header('WWW-Authenticate: Basic realm="Top Secret"');
# print 'Text that will be displayed if the user hits cancel or ';
# print 'enters wrong login data';
