I need to allow Arabic usernames on my website which is already using ctype_alnum to validate the username field. When I try to use Arabic usernames, the validation error message is returned. ctype_alnum does not recognize arabic characters as letters and numbers. How can i work around this ?

推荐答案

您可以使用此正则表达式查找所有阿拉伯字符:

You can find all Arabic Characters by using this Regex:

preg_match("/^[a-zA-Z\p{Cyrillic}0-9\s\-]+$/u", $string);

如果匹配的长度等于用户名长度，则它是一个阿拉伯用户名.

If the matched length equals the username length it is an arabic username.
