Hello, to all php guru out there. heheheh

i just like to asked for your help regarding parsing a domain i hope that you can help me with this..

i will give some of the examples that need to output on right way..

1. http://www.example.com/index.php

2. http://www.subdomain.example.com/index.php?cmd=1&page=2.......

3. www.example.com

4. subodomain.list1.example.com

5. www.example.com.au - needs to ouput example.com.au

All Output: example.com

Note that i need any tld i'm not specifiying one TLD or domain extensions.. and other thing is there are also 2 dot in tld like co.uk, com.ph and etc.... so i only need to get is the domain name..

I hope you can help me with this..

How do you make the difference between example.com.au and au.example.com ?

AOP Web Development

what do you mean?????????? hehehheh i guess

au.example.com - is subdomain right?

and example.com.au - is something like an extension of a tld representing countries..

is that what you mean?????

anyway i don't matter with that i just only need the output

MrBlueSky

I think what he means is this: when you process www.example.com.au, how do you know if it has to become example.com.au, or com.au? For a human this is easy: it should be the first. But that's because we know .au is a TLD which has sub-TLD's. A script doesn't know that.

To solve this, you'll have to provide a list of all possible TLD's to the script.

Another example, to make it clear:

www.message.msn.cx

Should the outcome be "msn.cx" or "message.msn.cx"?

yeah your right, im don't care regarding the tlds or what ever tlds i know that are a lot of tld and new tlds comes out... most specially with this are every country i guess have sub tlds. but don't know sure about it..

let say you have

www.example.gov.uk - example.gov.uk
www.example.co.uk - example.co.uk

http://subdomain2.subdomain1.example.com.au - example.com.au
http://subdomain.domain.gov.au - domain.gov.au
http://subdomain.list.au - list.au

here is the example of some tld but im not specifying that that are the only valid.. but what want is something like that more flexible to use
