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

array();if (isset($charArray[$char]) && count($charArray[$char]) != 0) {$nameArray = $charArray[$char];}array_push($nameArray, $name);$charArray[$char] = $nameArray;}ksort($charArray);echo
