Regular, for example: https:\/\/[^\s]*

see RFC 3986 (Section 2: Characters)

https?:\/\/[!#$&-;=?-[\]_a-z~]*

Good afternoon.
PHP has a global array $_SERVER .
And in this array there is an index "QUERY_STRING", which contains the data passed in the address after the "?"
There is also "HTTP_HOST", which contains the domain name.
There is a ton of stuff, follow the link and see what you can get out of this array.
Just do it on the right page print_r($_SERVER)and see what it gives you.
