PHP二维数组按照中文姓名首字母排序

方法一：

        直接排序不返回首字母

$old_list = $this->model->field('id, number, username, mobile')
        ->where('xxx', 'xxx')
        ->select();

foreach ($old_list as $key => $value) {
    $value['username'] = iconv('UTF-8', 'GBK', $value['username']);
    $new_list[$key] = $value;
}
array_multisort(array_column($new_list, 'username'), SORT_ASC, $new_list);

foreach ($new_list as $key => $value) {
    $value['username'] = iconv('GBK', 'UTF-8', $value['username']);
    $list [$key] = $value;
}

方法二：

        返回首字母的排序

public function test() {

        $list = $this->model->field('id, number, username, mobile')
        ->where('xxx', 'xxx')
        ->select();

        foreach ($list as $name) {
            $char = $this->getFirstChar($name['username']);
            $nameArray = array();
            if (isset($charArray[$char]) && count($charArray[$char]) != 0) {
                $nameArray = $charArray[$char];
            }
            array_push($nameArray, $name);
            $charArray[$char] = $nameArray;
        }
        ksort($charArray);

        echo '
';
        var_dump($charArray);

    }

    public function getFirstChar($s)
    {
        $s0 = mb_substr($s, 0, 3); //获取名字的姓
        $s = iconv('UTF-8', 'gb2312', $s0); // 将UTF-8转换成GB2312编码

        if (ord($s0) > 128) { //汉字开头，汉字没有以U、V开头的
            $asc = ord($s[0]) * 256 + ord($s[1]) - 65536;
