preg_match () vs htmlspecialchars()

[prkarpi]

I have a little dilemma. What could the difference be between preg_match() and htmlspecailchats() when using either one of them checking for html's INPUT in the browser. I find that it is easier to use preg_match() rather than htmlspecialchars() when eliminating slashes, quotes etc. Can someone give me some info on whether I am right or not.

Thanks.

htmlspecialchars replaces the 5 chars listed on the manual page, with preg_replace you can replace anything you choose.

*I assume you mean preg_replace
