M·C, IST: php root

Experience, to find home and uri
Home: http://web.ist.utl.pt/~mcasquilho
Uri: http://web.ist.utl.pt/~mcasquilho/text/php.php
Conclusion The easiest way to get the root seems to be (see table) the association of http_referer with, namely, php_self. The problem, however, is that http_referer is not reliable. [This can be verified if you enter this page directly (writing its address in the address bar).] The method is to get a substring of http_referer till the string that is common with php_self. In this site, this common string would be "/~mcasquil".

1) ps: ~mcasquilho/text/php.php % home: http://web.ist.utl.pt/~mcasquilho %
2) hr: % home: %

Http_referer:		(the calling page, if any)

Document_root:	/var/www/web.ist.utl.pt	--
• Http_host:	web.ist.utl.pt	Server variable
