Re: preg match

I'm not sure what you're trying to do with preg_match, since the parameters you send to it, are from the database, and an undeclared variable $msg(which is what exactly). Unless you give us examples of the arguments to preg_match, and what you expect the results should be, as well as what they are, we can't really be of much help. Having that said: You are using "/$chk_msg/" as the first parameter. since you are simply putting /'s around $chk_msg, this leads me to suggest that you don't need regex at all, and perhaps would be better using some of the string functions. strpos() ( http://www.php.net/strpos ) springs to mind. Just a few tips: As an aside, I notice that you are connecting to localhost:3306. Just incase you didn't know, when you connect to localhost through mysql_connect, assuming you are on a unix host, it uses a unix socket, regardless if you specify a port. If you want to override this behavour, and use TCP sockets, you can connect to 127.0.0.1.
