PHP Concatenate

Hi there,

Here is what I'm trying to do.. I'm trying to merge the first and last name (that I can do) into an email address. But what I'm trying to do is to drop the middle initial. If the entry was from a form, I would have no problem, but the data will be uploaded from a different source, how would I go about dropping the middle initial?

Would I use regex??

Thank you,
Kevin
