Rewrite URL using PHP

Question

Following is the Folder Structure of my PHP Project

PHPProject (Root)
-->Admin/
-->Config/
-->File1.php
-->File2.php
--> ..
--> ..
-->.htaccess
-->File10.php

I would like to enable RewriteURL for the project that can be accessed in the following manner.

Rule 1: My Domain should always be accessed with www.mydomain.com. If someone tries to access as http://mydomain.com i will have to rewrite the URL to http://www.mydomain.com. For which I am using the following rule on my htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#RewriteCond %{HTTP_HOST} !^www\.mydomain\.com [NC]
#RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]
</IfModule>

Rule 2: I would like to have a specific URL that points to a page:

http://www.mydomain.com/username to rewrite to http://www.mydomain.com/file4.php?name=username

Rule 3:

I am able to get the first rule to work properly with the above information on .htaccess file, but the problem is I have to hardcode the domain name on it. Would it be possible to specify a generic (regex) so that the rule applies to multiple domain?

Question: I require help to combine Rule 1 + Rule 2 + Rule 3 altogether as rules on my .htaccess file.

Could someone please help me acheive this.

Rule 1:

RewriteCond %{HTTP_HOST} !^www\.(domain1|domain2|domain3|domain4)\.com [NC]
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]

or:

RewriteCond %{HTTP_HOST} !^www\.domain1\.com [NC]
RewriteCond %{HTTP_HOST} !^www\.domain2\.com [NC]
RewriteCond %{HTTP_HOST} !^www\.domain3\.com [NC]
RewriteCond %{HTTP_HOST} !^www\.domain4\.com [NC]
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]

Rule 2

http://www.mydomain.com/username

to

http://www.mydomain.com/file4.php?name=username

RewriteRule ^username$ /file4.php?name=username [QSA,NC,L]

and if you want to make it generic (with alphanum chars):

RewriteRule ^([a-z0-9]+)$ /file4.php?name=$1 [QSA,NC,L]

Rule 3

Get all together:

RewriteCond %{HTTP_HOST} !^www\.(domain1|domain2|domain3|domain4)\.com [NC]
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]

RewriteRule ^([a-z0-9]+)$ /file4.php?name=$1 [QSA,NC,L]

Hope this helps.

Two hints:

Please try to use the RewriteLog directive: it helps you to track down such problems:

# Trace:
# (!) file gets big quickly, remove in prod environments:
RewriteLog "/web/logs/mywebsite.rewrite.log"
RewriteLogLevel 9
RewriteEngine On

My favorite tool to check for regexp:

If you only need it for http, this should do.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST}!^(www\.¦$) [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

And, For the rest you can use the Front Controller Pattern.

[Idea of Front Controller Pattern is redirects all your request to a php file and decide from there]

Follow the following urls, then if you have any question, you can ask :)
