在php中301重定向实现方法很简单我们只要简单的利用header发送301状态代码,然后再用header进行跳转,效果与apache,iis,nginx都是一样的效果哦。
一:更推荐这种方法,因为它可以把www.vcphp.com原来所有的url都转到vcphp.com新的地址上,代码如下:
- <?php
- $the_host = $_SERVER['HTTP_HOST'];
- $request_uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';
- if($the_host == 'www.vcphp.com')
- {
- header('HTTP/1.1 301 Moved Permanently');
- header('Location: http://vcphp.com'.$request_uri);//
- }
- ?>
二:单页多站的Php301重定向代码,www.vcphp.com和vcphp.com则301到index.php上,www.vcphp.com则301到vcphp.com上,否则转到错误页,代码如下:
- if(($HTTP_HOST=="www.vcphp.com")or($HTTP_HOST=="vcphp.com"))
- {
- header("HTTP/1.1 301 Moved Permanently");
- Header("Location: /index.php");
- }
- elseif($HTTP_HOST=="www.vcphp.com")
- {
- header("HTTP/1.1 301 Moved Permanently");
- Header("Location: http://vcphp.com");
- }
- else
- {
- Header("Location: /404.htm");
- }
附上其它跳转办法,代码如下:
-
- header( 'Content-Type:text/html;charset=utf-8 ');
-
- header('Content-type: application/atom+xml');
-
- header('Content-type: text/css');
-
- header('Content-type: text/javascript');
-
- header('Content-type: image/jpeg');
-
- header('Content-type: application/json');
-
- header('Content-type: application/pdf');
-
- header('Content-Type: application/rss+xml; charset=ISO-8859-1');
-
- header('Content-type: text/plain');
-
- header('Content-type: text/xml');
-
- header('HTTP/1.1 200 OK');
-
- header('HTTP/1.1 404 Not Found');
-
- header('HTTP/1.1 301 Moved Permanently');
-
- header('Location: http://www.example.org/');
-
- header('Refresh: 10; url=http://www.example.org/');
- print 'You will be redirected in 10 seconds';
-
-
-
- header('X-Powered-By: PHP/4.4.0');
- header('X-Powered-By: Brain/0.6b');
-
- header('Content-language: en');
-
- $time = time() - 60;
- header('Last-Modified: '.gmdate('D, d M Y H:i:s', $time).' GMT');
-
- header('HTTP/1.1 304 Not Modified');
-
- header('Content-Length: 1234');
-
- header('Content-Type: application/octet-stream');
- header('Content-Disposition: attachment; filename="example.zip"');
- header('Content-Transfer-Encoding: binary');
-
- readfile('example.zip');
-
- header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
- header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
- header('Pragma: no-cache');
-
- header('Content-Type: text/html; charset=iso-8859-1');
- header('Content-Type: text/html; charset=utf-8');
- header('Content-Type: text/plain');
- header('Content-Type: image/jpeg');
- header('Content-Type: application/zip');
- header('Content-Type: application/pdf');
- header('Content-Type: audio/mpeg');
- header('Content-Type: application/x-shockw**e-flash');
-
- 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';
跳转要注意以下几点,有助于解决一些新手经常遇到的问题
1、location和“:”号间不能有空格,否则会出错。
2、在用header前不能有任何的输出。
3、header后的PHP代码还会被执行。
