这是我的前端代码：
2
594<form action="" method="post">
<input type="file" name="image" class="input">
</form>
和控制器：
$upload_image = $_FILES['image']['name'];
if ($upload_image) {
$config['allowed_types'] = 'xml|docx|jpg|png|pdf|xlsx';
$config['max_size'] = '999999';
$config['upload_path'] = './assets/img/image/';
$this->load->library('upload', $config);
if ($this->upload->do_upload('image')) {
$new_image = $this->upload->data('file_name');
$this->db->set('image', $new_image);
} else {
echo $this->upload->display_errors();
}
}
在 $config 中，prog 知道刚刚输入的文件类型，例如 img docx 等，我如何获取刚刚作为 $types 输入的文件类型？

如果您询问如何获取刚刚提交的文件的文件类型，这很简单，您只需使用
