Php实现301重定向跳转代码

accomplish Jump Redirect

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.phprm.com原来所有的url都转到phprm.com新的地址上,代码如下:

<?php
$the_host = $_SERVER[&#39;HTTP_HOST&#39;];
$request_uri = isset($_SERVER[&#39;REQUEST_URI&#39;]) ? $_SERVER[&#39;REQUEST_URI&#39;] : &#39;&#39;;
if ($the_host == &#39;www.phprm.com&#39;) {
    header(&#39;HTTP/1.1 301 Moved Permanently&#39;);
    header(&#39;Location: http://phprm.com&#39; . $request_uri); //
    
}
?>
Copy after login

二:单页多站的Php301重定向代码,www.phprm.com和phprm.com则301到index.php上,www.phprm.com则301到phprm.com上,否则转到错误页,代码如下:

<?php
if (($HTTP_HOST == "www.phprm.com") or ($HTTP_HOST == "phprm.com")) {
    header("HTTP/1.1 301 Moved Permanently");
    Header("Location: /index.php");
} elseif ($HTTP_HOST == "www.phprm.com") {
    header("HTTP/1.1 301 Moved Permanently");
    Header("Location: http://phprm.com");
} else {
    Header("Location: /404.htm");
}
?>
Copy after login

附上其它跳转办法,代码如下:

<?php
//定义编码
header(&#39;Content-Type:text/html;charset=utf-8 &#39;);
//Atom
header(&#39;Content-type: application/atom+xml&#39;);
//CSS
header(&#39;Content-type: text/css&#39;);
//Javascript
header(&#39;Content-type: text/javascript&#39;);
//JPEG Image
header(&#39;Content-type: image/jpeg&#39;);
//JSON
header(&#39;Content-type: application/json&#39;);
//PDF
header(&#39;Content-type: application/pdf&#39;);
//RSS
header(&#39;Content-Type: application/rss+xml; charset=ISO-8859-1&#39;);
//Text (Plain)
header(&#39;Content-type: text/plain&#39;);
//XML
header(&#39;Content-type: text/xml&#39;);
// ok
header(&#39;HTTP/1.1 200 OK&#39;);
//设置一个404头:
header(&#39;HTTP/1.1 404 Not Found&#39;);
//设置地址被永久的重定向
header(&#39;HTTP/1.1 301 Moved Permanently&#39;);
//转到一个新地址
header(&#39;Location: http://www.example.org/&#39;);
//文件延迟转向:
header(&#39;Refresh: 10; url=http://www.example.org/&#39;);
print &#39;You will be redirected in 10 seconds&#39;;
//当然,也可以使用html语法实现
// <meta http-equiv="refresh" content="10;http://www.example.org/ />
// override X-Powered-By: PHP:
header(&#39;X-Powered-By: PHP/4.4.0&#39;);
header(&#39;X-Powered-By: Brain/0.6b&#39;);
//文档语言
header(&#39;Content-language: en&#39;);
//告诉浏览器最后一次修改时间
$time = time() - 60; // or filemtime($fn), etc
header(&#39;Last-Modified: &#39; . gmdate(&#39;D, d M Y H:i:s&#39;, $time) . &#39; GMT&#39;);
//告诉浏览器文档内容没有发生改变
header(&#39;HTTP/1.1 304 Not Modified&#39;);
//设置内容长度
header(&#39;Content-Length: 1234&#39;);
//设置为一个下载类型
header(&#39;Content-Type: application/octet-stream&#39;);
header(&#39;Content-Disposition: attachment; filename="example.zip"&#39;);
header(&#39;Content-Transfer-Encoding: binary&#39;);
// load the file to send:
readfile(&#39;example.zip&#39;);
// 对当前文档禁用缓存
header(&#39;Cache-Control: no-cache, no-store, max-age=0, must-revalidate&#39;);
header(&#39;Expires: Mon, 26 Jul 1997 05:00:00 GMT&#39;); // Date in the past
header(&#39;Pragma: no-cache&#39;);
//设置内容类型:
header(&#39;Content-Type: text/html; charset=iso-8859-1&#39;);
header(&#39;Content-Type: text/html; charset=utf-8&#39;);
header(&#39;Content-Type: text/plain&#39;); //纯文本格式
header(&#39;Content-Type: image/jpeg&#39;); //JPG***
header(&#39;Content-Type: application/zip&#39;); // ZIP文件
header(&#39;Content-Type: application/pdf&#39;); // PDF文件
header(&#39;Content-Type: audio/mpeg&#39;); // 音频文件
header(&#39;Content-Type: application/x-shockw**e-flash&#39;); //Flash动画
//显示登陆对话框
header(&#39;HTTP/1.1 401 Unauthorized&#39;);
header(&#39;WWW-Authenticate: Basic realm="Top Secret"&#39;);
print &#39;Text that will be displayed if the user hits cancel or &#39;;
print &#39;enters wrong login data&#39;;
?>
Copy after login

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。
