Hello world1

Hi. I'm a recent adopter of php, and I am coming to love it.

I am building a website. I need to accept a form, and it is to accept ONLY letters and numbers; just 1 char of anything else and it must bark like a rabid duck and abort the process. whats the simple reliable way to do this?

PS: I rent a slice off the end of the box, and cannot play around with configuring things.



Salute!
