Hey, I know that in a URL there's generally the "scheme" (i.e. http://),
followed by the hostname or domain name (i.e. en.wikipedia.org/)
followed by possible subfolders (i.e. /wiki/) which can then be
followed by the name of a file to send the request to (i.e. index.html
or index.php or something). There can also be GET data (i.e. ?
name=value) and the anchor thing (i.e. #Chapter_1). But also,
frequently there's just a string that finishes the URL, which doesn't
appear to be a folder (no trailing forward slash) or a file (no
extension), for example:
http://en.wikipedia.org/wiki/Uniform_Resource_Locator
Can someone explain to me what this string (i.e.
"Uniform_Resource_Locator" in the above example) is, and how you can
use php to get it?
Thanks.
