Hi,
I'd like to let a regular link through:
http://www.mysite.com/section/page2-name.php
What I was doing is denying characters etc
if (preg_match('/[?&%=;]/', $addr)) exit;
But, the recommended way is to allow characters you want through
[a-zA-Z0-9 / : _ .-] thus blocking the rest.
I know some may need escaping, and the dash is awkward,
but I just can't seem to get it correct.
Thanks, Bob.

Hi Bob,
It is much faster to do this sort of thing without REGEX -
if (strlen(strspn(strtolower($addr),
"abcdefghijklmnopqrstuvwxyz0123456789/_.-")) != strlen($addr))
{
// exit; string not valid
}
Thanks, Rob.
