How does that match "Firstname Lastname" better than a regex? That will
return true as long as there is at least one space, no matter what the
rest of the submission is. I could submit "$^&#^&$&#& )(*!@#", or I
could submit just a single space, and that would return true. strpos()
has it's uses, but this isn't one of them.
There is a large number of sittuations that the regex won't work in.
Special characters aren't included (from what I can understand using my
weak regex knowlege), you could even be chinese, and it wouldn't work.
If you use strpos with trim and strlen cleverlly, you won't have to
worry about it again.
My $0.02
You can trim whitespace and check the length until the cows come home,
and that still won't stop a string such as "#T*& a%@!". A regex can
cover practicaly every situation for a name submission; it all depends
on how deep you want to validate. strpos() has too narrow of a scope to
match a complex pattern.
