Accept accents in a PHP form

Question

In my form, i do some verifications before registering in database

    if( isset($form['lastname']) && !empty($form['lastname']) && !preg_match ('/[^a-z]/i', $form['lastname']))

{

}

this does not accept accents like "benoît" or "hélène"

Does anyone know to make them allowed ? thanks in advance

Omit the `prey_match` check? What is it for? What do you want to allow and what do you want to disallow? — deceze, Jan 03 '13 at 13:50
It also doesn't accept `O'Brien` or `Reece-Jones`, or any number of other valid names. And that's just common English names. Bottom line: Don't even attempt to validate people's names.

French accents, as same as German Umlauts etc. are words beyond A-Z.

If you need to filter numbers (0-9), you can use smth. like this (not recomended).

if( isset($form['lastname']) && !empty($form['lastname']) && !preg_match ('/[^0-9]/i', $form['lastname'])) {

}

The question is: can you be certain that no-one has a name that contains a digit? *Absolutely* certain?? Sure, John Smith III may use roman numerals for his name, but that's just convention; what's to stop someone else deciding to use "The 3rd" instead? – SDC Jan 03 '13 at 14:19
