I read all this post please tell us what you want to do bugging me lol...............
And this was the safe way to use get but each page has to have a condition=in the link ok.
say on index.php you have these three links for your site
<a href="links.php?h=home">my home page</a>// for home page
< a href="links.php?f=forum">my forum page</a>//for the forum page
<a href="links.php?c=contact">contact me</a>// contact admin page
All the above links goto a page called links.php and know we call the links with the $_GET[' '] statement also the above was a html version ok and is also a safe way to use $_GET[' '].
Know on the page links.php you gotto use the $_GET[' '] statement.
echo"sorry you have not got any right to be on this page";
