最近碰到一个fgetcsv处理带中文的csv（由excel生成）的场景出现问题。表现为截取长度不对， 有两个纯中文字段没有被拆分， 貌似是fgetcsv不认中文的缘故，看了http://blog.163.com/ybbqg@126/blog/static/12236641620115143124763/ 这篇文章发现方法二可行

现将方法二的代码贴出来，作为备忘

function fgetcsv_reg(& $handle, $length = null, $d = ',', $e = '"') {
    $d = preg_quote($d);
    $e = preg_quote($e);
    $_line = "";
    $eof=false;
    while ($eof != true) {
        $_line .= (empty ($length) ? fgets($handle) : fgets($handle, $length));
        $itemcnt = preg_match_all('/' . $e . '/', $_line, $dummy);
        if ($itemcnt % 2 == 0)
            $eof = true;
    }
    $_csv_line = preg_replace('/(?: |[ ])?$/', $d, trim($_line));
    $_csv_pattern = '/(' . $e . '[^' . $e . ']*(?:' . $e . $e . '[^' . $e . ']*)*' . $e . '|[^' . $d . ']*)' . $d . '/';
    preg_match_all($_csv_pattern, $_csv_line, $_csv_matches);
    $_csv_data = $_csv_matches[1];
    for ($_csv_i = 0; $_csv_i < count($_csv_data); $_csv_i++) {
        $_csv_data[$_csv_i] = preg_replace('/^' . $e . '(.*)' . $e . '$/s', '$1', $_csv_data[$_csv_i]);
        $_csv_data[$_csv_i] = str_replace($e . $e, $e, $_csv_data[$_csv_i]);
    }
    return empty ($_line) ? false : $_csv_data;
}
