Creating subdomains through PHP

[usgoel]

Hi friends!

I need some help in creating subdomains through PHP script.

My host permits me to create unlimited subdomains under my domain through the cpanel.

I wanna know how do we create subdomains using php script so that my users fill in a simple form on my site and submitting it, creates a new sub domain.

Thanks in Advance for your kind help!!!!!!! :o

you probably wont be able to do it with php because it wont have access to the apache conf file or the dns zone file which would need to be changed in order to add the subdomain. the cleanest way to do this in my opinion is to just have your host set up a wildcard for you in the apache config file, and have it point to a folder of yours where you can set up the script that deals with what subdomain was visited and show the appropriate page.

the virtualhost entry might look something like this

<VirtualHost 1.2.3.4>
ServerAlias *.yoursite.com
ServerAdmin [e-mail]
DocumentRoot /home/yoursite/public_html/subdomains
</VirtualHost>

now when someone access any subdomain it loads the index page from the subdomains folder, in there you put your php script that serves the appropriate content. you can determine which subdomain they visited by using $_SERVER['HTTP_HOST'] and seeing which subdomain was accessed.
