This article to you to share is the use of PHP validation string in the Chinese language method, very simple and practical, the need for small partners can refer to the following

PHP uses Preg_match to match and determine whether a string contains Chinese or Chinese in the following way:

$str = ' php Chinese web '; if (Preg_match ('/[\x7f-\xff]/', $str)) {echo ' string has Chinese <br/> ';} else{echo ' string does not have Chinese <br/> ';} if (Preg_match ('/^[\x7f-\xff]+$/', $str)) {echo ' string is all Chinese ';} else{echo ' string is not all Chinese ';}

The result of the above program output is:

The string has Chinese
The string is not all Chinese

Both the Utf-8 and GBK codes are tested and can be used.
