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.
