url_segment( ) 

Returns the different segments of an url.

A very Handy and must use tool for analyzing Urls e.g. url_segment('http://username:password/path/to/file?arg=valueanchor', 'host') If no url is given it takes the current url as the requested url would return separate segment of the url according to given argument For example

scheme => http
 host => hostname
 user => username
 pass => password
 path => /path
 query => arg=value
 fragment => anchor

If you use url_segment(0) or url_segment(1) It will return firstPart and secondPart /firstPart/secondPart.

Parameters:

	$url	string
	$segment	mixed

Returns:

mixed
