Matching Unicode letter characters in PCRE/PHP

Question

I\'m trying to write a reasonably permissive validator for names in PHP, and my first attempt consists of the following pattern:

// unicode letters, apostrop         


        

Answer 1

I think the problem is much simpler than that: You forgot to specify the u modifier. The Unicode character properties are only available in UTF-8 mode.

Your regex should be:

// unicode letters, apostrophe, hyphen, space
$namePattern = '/^[-\' \p{L}]+$/u';
