Find occurences of unicode characters in string

Posted on 16th Feb 2014 07:03 pm by admin

I need to prohibit filenames with everything but English characters and numbers but regexp and string function don't seem to work because they consider the Greek alphabet letters as part of the A-Z a-z sequence. Here's what I've tried:

Quote:if (strspn($str, "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789") != strlen($str))
{
echo 'invalid filename';
}

Quote:if (!preg_match("/^([-a-z0-9])+$/i", $str))
{
echo 'invalid filename';
}
