Finding Single Char With ereg()


samman

Recommended Posts

I am using ereg() to filter out spam from a form on our website. All has worked well, until recently. I have been successful with expressions such as, "^mail", "^test", "^user", ... "adshost.info$", "adshost.com$", "adshost.org$". Now I am needing to be able to find a single character (example: "m") at the beginning of an email address (example: "m@spam_mail.com"). It needs to only find one char, and if there are others (like "mary"), it needs to let it go. I have tried "^m", "^m$", "^.$" (and a few others), but none are working. Can someone lend me a hand?

Thanks,
Sam
