SUBSTR can only be used to intercept single-byte encoded strings, which can be garbled when using substr to intercept multibyte strings:

Cases:

$a = "Baidu, you are Zhan";#echo substr ($a, 0, 5). Php_eol; Garbled: Hundred 庍#echo substr ($a, 0, strlen ($a));//Use SUBSTR to truncate the string and not garbled if the entire field is completely intercepted//best solutionEcho Mb_substr($a, 0, Ten, "UTF-8"); //Baidu a bit, you are Zha
