使用CI遇到字符编码问题utf8.php中@iconv('UTF-8', 'UTF-8//IGNORE', $str)转码失败

Question

使用CI遇到字符编码问题utf8.php中@iconv('UTF-8', 'UTF-8//IGNORE', $str)未转码成功，导致$_POST数据被清除，需使用mb_convert_encoding才可以

  $str = '问题，iconv为什么转码不成功，多谢大佬！！';

    $strIconv = @iconv('UTF-8', 'UTF-8//IGNORE', $str);

    $strMbConvert = mb_convert_encoding($str, 'UTF-8', 'UTF-8');

    echo 'str-iconv:'.$strIconv;
    echo "<br>";
    echo 'str-mb-convert:'.$strMbConvert;
