PHP中trim 会导致中文乱码的解决方案

为什么80%的码农都做不了架构师？>>>   

function mb_rtrim($string, $trim, $encoding)
{
 
    $mask = [];
    $trimLength = mb_strlen($trim, $encoding);
    for ($i = 0; $i < $trimLength; $i++) {
        $item = mb_substr($trim, $i, 1, $encoding);
        $mask[] = $item;
    }
 
    $len = mb_strlen($string, $encoding);
    if ($len > 0) {
        $i = $len - 1;
        do {
            $item = mb_substr($string, $i, 1, $encoding);
            if (in_array($item, $mask)) {
                $len--;
            } else {
                break;
            }
        } while ($i-- != 0);
    }
 
    return mb_substr($string, 0, $len, $encoding);
}
 
mb_internal_encoding("UTF-8");
$tag = "互联网产品、";
$encoding = mb_internal_encoding();
print_r(mb_rtrim($tag, "、",$encoding));
