Finally, use substr() to extract the piece that you wanted. Example: $url_array = parse_url('http://zed2.mdah.state.ms.us/F/CC8V7H1JF4LNBVP5KARL4KGE8AHIKP1I72JSBG6AYQSMK8YF4Y-01471?func=find-b-0'); $slash_pos = strrpos($url_array['path'],'/'); $session_ID = substr($url_array['path'],$slash_pos+1); /sylikc
