An interesting read, Salathe. Thanks for pointing me in the right direction! Before last night I've only managed to read the first few pages of any regular expression documentation. There is some excellent stuff in php.net's manual for regular expressions, such as all the \S, \n.

I know it's not really much of an issue with the numeric items, but I was merely wondering if there was a flag you could set which prevented it. I'm guessing there isn't, though.
