.htaccess带有随机参数的URL重写

Question

I'm currently writing a PHP app and am about to create various controllers. Currently I have one controller with certain method, so the URL looks like this:

http://somewebsite.com/index.php?c=controller&a=action

It's being rewritten to this:

http://somewebsite.com/controller/action

With this .htaccess file:

RewriteEngine On
RewriteRule ^([a-z]+)/([a-z]+)$ index.php?c=$1&a=$2 [NC]

What I want to achieve is the ability to rewrite URL with more than one controller (the more, the better), possibly in random order. Is there a more convenient way than rewriting every possible combination of URL parameters?

Answer 1

Many frameworks (Codeigniter, WordPress, Laravel, etc.) use an .htaccess file similar to the following:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

This rewrites all incoming URLs to be handled by the index.php file. You can then use $_SERVER['REQUEST_URI'] variable to get the exact request URI, parse it, and then handle it how you want.

如果您要使用任意路由方案，则最好的选择是将整个url字符串（例如^（。+）$）传递给index.php，然后让您的php应用程序基于'/'分割字符串并处理但是数组对您的应用程序有意义
