Consider what you'd mark as a full url, do you want to accept ftp://
and such links as well.. quite generic, I'd go for smth like:
/^([a-z]+):\/\/(([\w\.]+)\.([a-z]{2,3}))(:(\d+))?(\/.*)?$/
Which would give you:
Array
(
[0] => ftp://www.example.com.com.uk:88/something/to/remember
[1] => ftp
[2] => www.example.com.com.uk
[3] => www.example.com.com
[4] => uk
[5] => :88
[6] => 88
[7] => /something/to/remember
)
Here're seme things I didn't take into account:
* double dots (www...example..com)
* double slashes (www.example.com//asdfasf//asdfasf)
* check for protocol validity, might wanna change the first part to
(ftp|http|chrome|.. any protocol you want to accept)
* I left everything after the first slash completely to the
imagination of your input data - this can contain pretty much anything
anyways
* login details (user:[EMAIL PROTECTED])
If you want to have a full regex that is really complete, check out:
http://www.foad.org/~abigail/Perl/url3.pl, and execute it .. (linked
from http://www.foad.org/~abigail/Perl/url2.html)
Enjoy!
