Re: [PHP] regex - filtering out chinese utf8 characters
Hi Merlin, I think the pattern you're looking for is '/[a-zA-Z0-9]/' which will match all alphanumeric characters.

[PHP] regex - filtering out chinese utf8 characters
Hi there, I am trying to filter out content that is not ascii. Can I do this with regex? For example: $regex = '[AZ][09]'; if (preg_match($regex, $text)) { return TRUE; } else { return FALSE; } The reason I need to do this is that I am doing a mysql query with the text and I need to make sure it is not UTF8. Otherwise I do get following error: Error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' I am new to regex and would be happy for a jump start to get this fixed.
