Hello Hans,
Thanks for the welcome. :)
Okay, I use PCRE type functions for regular expressions so I think I
can continue using them without worrying about the speed.
Yes, I never thought if i had to support a different character sets.
Thanks for pointing out the possibilities.
Sincerely,
Yogesh

Hi Yogesh and welcome.
I have a simple question. I want to validate first and last name. I
assume that these are probably most common fields in any type of
registration forms on websites.
When I validate these fields, I can't use ctype_alpha since these don't
allow ' as in O'Reilly or Last Name with white space in it. I have to
use a regular _expression_ here. That's fine and I use it as well. Another
method is to find a single ' or space, trim it and then validate
remaining alphabet characters. RegEx is slower and even in new
filter_input, there is no way to validate these field types.
I wouldn't worry too much about the speed of regex (I'd recommend pcre_*
functions).
Is there any other way to validate first and last names. It will be nice
to have have inbuilt function for such commonly used field types. I will
like to know how people tackle these issue.
But note that validating is all relative. What if you need to support
various charsets? I typically just check for strings without newlines and
non-printable chars. For international sites, obviously, there are some
other loops involved.
