I am looking for a function that checks there isn't non-valid URL
characters in some input:

http://www.blooberry.com/indexdot/html/topics/urlencoding.htm

Not sure what happened to the % character here.

I am having trouble crafting the regular expression as of course:

if (preg_match("/[^a-zA-Z0-9$-_.+!*'(),]/", $uri))

doesn't work and no end of escaping seems to work.
