how to create virtual dymanic subdomain in php with .htaccess

I need to create virtual subdomain.
For example my site is www.xyz.com

i need to have abc.xyz.com were the abc may be the username ...

I know we can do this with the help of .htaccess

Can anyone help ?

 

try google "dynamic subdomains"

 

Something like:

Options +FollowSymLinks
Options +Indexes
RewriteEngine On
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{HTTP_HOST} !^www\.yourdomain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+)\.yourdomain\.com$ [NC]
RewriteRule (.*) /redir/$1 [L]

Code (markup):

This will redirect any.yourdomain.com to yourdomain/redir/any. You can play with the code a bit if you need to. Also, the \'s in the domain names are required, so don't remove them.

not working, showing file not found error

 

I am ready to pay, if any one give me the correct solution. I need to solutions in php

 

#rewrite conditions
RewriteCond %{HTTP_HOST} !^(YOUR_DOMAIN\.com)$ [NC]
RewriteRule ^(.*)$ script/index.php?$1

This rewrite rule directs any subdomain requests to a file named /script/index.php on the local server.

That script file can use the $_SERVER["QUERY_STRING"] parameter to see what virtual subdomain the request was for and redirect the user correctly, or just provide content for the requested subdomain.

The rule as written will redirect all requests with a subdomain, even www, to the script file.

 

and make a subdomain and name it *

and add the .htaccess file to it's folder

 

Try this

RewriteEngine On
Options +FollowSymlinks
RewriteCond %{ENV:REDIRECT_MYFLAG} ^$
RewriteCond %{HTTP_HOST} ^([A-Za-z0-9]*)\.site\.com$
RewriteRule ^(.+) %{HTTP_HOST}$1 [E=MYFLAG:1]
RewriteRule ^([A-Za-z0-9]*)\.site\.com(.*) /([A-Za-z0-9]*)%{REQUEST_URI} [L]

PHP:
