漂亮的URL通过htaccess使用任意数量的参数

Question

Actually i have this URL:

http://www.example.com/index.php?site=contact&param1=value1&param2=value2&param3=value3

But i want to have this URL format:

http://www.example.com/contact/param1:value1/param2:value2/param3:value3

So the "contact" goes to variable $_GET["site"] and rest of parameters should be able to access via $_GET["param1"], $_GET["param2"] etc. The problem is, it has to work with any number of parameters (there could be param4 or even param50 or any other name of parameter). Is it possible via htaccess to cover all these cases?

Answer 1

This is entirely doable using some creative htaccess and PHP. Effectively what you are doing here is telling Apache to direct all page requests to index.php if they are not for a real file or directory on the server...

## No directory listings
IndexIgnore *

## Can be commented out if causes errors, see notes above.
Options +FollowSymlinks
Options -Indexes

## Mod_rewrite in use.

RewriteEngine On

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php [L]

After this all you need to do is go into PHP and access the full user requested URL structure using the $_SERVER['REQUEST_URI'] superglobal and then break it down into an array using explode("/", $_SERVER['REQUEST_URI']).

I currently use this on a number of my sites with all of the sites being served by index.php but with url structures such as...

which is then processed by the explode command to appear in an array as... 0=>"forums", 1=>"11824-some-topic-name",2=>"reply"
