php preg_match characters

Question

I need help with preg_match function in php. I have read a lot of answers on SO, but I can't get any needed information.

So, I would like that preg_match check for characters az, AZ, 0-9, special characters č, š, ž, đ, ć, Č, Š, Ž, Đ, Ć and ? " # $ % & / ( ) =. * ° ' + - *, ; - _: : ? " # $ % & / ( ) =. * ° ' + - *, ; - _: :

For first part (az, AZ, 0-9) I saw how it is done, but for next part I don't have idea.

Answer 1

Simply list all characters in a character class :

[a-zA-Z0-9čšžđćČŠŽĐĆ!"#$%&/()=?*°'+*.,_;:-]

Since the minus sign bears special semantics, I moved it to the end where it, well, doesn't have special semantics . Make sure your editor encoding matches the input encoding (ie use UTF-8 everywhere).

By the way, that list is really excessive. You may want to simply use \w , which stands for an arbitrary word character , or \S (anything but whitespace).
