PHP randomly intercepts Chinese characters

Today I will share with you how to use PHP’s own method to intercept Chinese characters. Please note that the methods of intercepting Chinese characters and intercepting characters are different, because a Chinese character will occupy a different number of characters due to different encodings, and it will be 2 or 3 characters! Let me talk about the specific method:                                                                   Array, first parameter It is a regular match, and u must be added, because it is UTF8 encoding

// You cannot use substr or MB_SUBSTR here, because these methods are effective for characters, Chinese characters account for 2 or 3 characters

$str = preg_split('//u', $str, -1, PREG_SPLIT_NO_EMPTY); // The str_shuffle function cannot be used because that It’s about shuffling the characters

                                                            ‐ ‐ ‐ ‐ ‐ ‐ ‐ ‐ to

                    $str = array_slice($str, 0,4); $str = 'Youer Romantic Sakura Wang Jinsheng ';

getH($str);

?>

Although today's tutorial is very simple, the functions are still very practical.
