推荐答案

您不能改写一个号码的名称，除非你有把这一数字为名称的一些方法。这意味着，在HTTP守护进程级别（阿帕奇/ htaccess的），你没有足够的信息来重定向。在PHP中的重定向，请参阅这个。

You cannot rewrite a number to a name, unless you have some way of translating that number to a name. This means that on the http deamon level (Apache/.htaccess) you don't have enough information to redirect it. For redirects in php, see this.

既然你问在PHP重写，我来回答这个问题了。有没有这样的事情在一个PHP文件重写。内部重写映射一个网址（例如： www.domain.com/category/cat-name ），并让服务器执行不同的URL（例如： WWW .domain.com / category.php？ID = 13 ）。这发生在HTTP守护程序级别，你的情况阿帕奇。

Since you ask about rewrites in php, I'll answer that too. There is no such thing as rewriting in a php file. An internal rewrite maps one url (e.g. www.domain.com/category/cat-name) and lets the server execute a different url (e.g. www.domain.com/category.php?id=13). This happens on the http deamon level, in your case Apache.

首先做出的.htaccess在您的www根：

First make a .htaccess in your www-root:

RewriteEngine on
RewriteRule ^category/[^/]+$ /category.php

在category.php：

In category.php:

if( strpos( $_SERVER['REQUEST_URI'], 'category.php' ) != FALSE ) {
  //Non-seo url, let's redirect them
  $name = getSeoNameForId( $_GET['id'] );
  if( $name ) {
    header( "Location: http://www.domain.com/category/$name" );
    exit();
  } else {
    //Invalid or non-existing id?
    die( "Bad request" );
  }
}

$uri = explode( '/', $_SERVER['REQUEST_URI'] );
if( count( $uri ) > 1 ) {
  $name = $uri[1];
} else {
  //Requested as http://www.domain.com/category ?
  die( "Bad request" );
}

这将请求重定向到的类别/名称，如果你要求category.php？ID =数字和网址，如果你要求的类别/名称获取名称

This will redirect requests to category/name if you request category.php?id=number and get the name from the url if you request category/name
