Question

我知道如何进行URL重写，例如： www.example.com/index.php?id=1&cat=3到www.example.com/1/3/（或其他）。我知道。

我不知道的是如何在所有页面中更改我的所有链接以链接到漂亮的URL。我所有网站的链接都是旧时尚（<a href="index.php?id=1&cat=2">），而且还有很多。

如果用户点击index.php？id = 1，我问是否有人有想法或知道如何自动重定向到那个漂亮的URL。（如果你在网址中更改标题，几乎就像这个网站Stackoverflow一样。）

所以我的预言是......

使用.htaccess读取index.php？id = 1＆amp; cat = 2来重写索引/ 1/3本身再次解释（奇怪）
一个php文件，用于执行htaccess重写为原始重定向的重定向...

结论：将<a href="index.php?id=1&.....">自动更改为index/1/2

# This turns index.php?id=1&cat=2 into index/1/2 and then back 'transparent' into    index.php?id=1&cat=2 if you have old fashioned
# links in your site and don't want to change them :)


# Avoid mod_rewrite infinite loops 
# This is critical if you want to use this code

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

# Hard-rewrite ("[R]") to "friendly" URL.
# Needs RewriteCond to match original querystring.
# Uses "?" in target to remove original querystring,
#   and "%n" backrefs to move its components.
# Target must be a full path as it's a hard-rewrite.
RewriteCond %{QUERY_STRING} ^id=(\d+)&cat=(\d+)$
RewriteRule ^index.php$ http://localhost/index/%1/%2/? [L,R]

# Soft-rewrite from "friendly" URL to "real" URL.
# Transparent to browser.
# Won't re-trigger the above rewrite, though I'm
#   not really sure why! The order of the rules
#   doesn't seem to make a difference.
RewriteRule ^index/(\d+)/(\d+)/$ index.php?id=$1&cat=$2 [L]

Answer 1

RewriteEngine on

# Prevents browser looping, which does seem
#   to occur in some specific scenarios. Can't
#   explain the mechanics of this problem in
#   detail, but there we go.
RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

# Hard-rewrite ("[R]") to "friendly" URL.
# Needs RewriteCond to match original querystring.
# Uses "?" in target to remove original querystring,
#   and "%n" backrefs to move its components.
# Target must be a full path as it's a hard-rewrite.
RewriteCond %{QUERY_STRING} ^id=(\d+)&cat=(\d+)$
RewriteRule ^index\.php$ http://example.com/index/%1/%2/? [L,R]

# Soft-rewrite from "friendly" URL to "real" URL.
# Transparent to browser.
RewriteRule ^index/(\d+)/(\d+)/$ /index.php?id=$1&cat=$2

当然，理想情况下，您只需修复链接，然后您只需要进行软重写。：）

_{使用Apache / 2.2.3进行测试。我认为我编写了“硬重写”和“软重写”这两个术语。}

Answer 2

为什么不直接更改index.php文件呢？理论上，您可以通过这种方式进行更多错误检查，允许变量按任意顺序排列并仍然路由到正确的结束位置。

<?php
    // Permanent redirection
    header("HTTP/1.1 301 Moved Permanently");
    header("Location: http://www.example.com/{$_GET['id']}/{$_GET['cat']}");

我这里没有做任何错误检查，但是想给出一个基础示例。

第二个想法我想这是在index.php文件中增加了你想要用于你的应用程序本身的功能，所以它可能最终会混淆代码中的功能。
