laravel5 上传视频功能在本地实现

    **<?php
    ********namespace** App\Traits\FileUploads;
    
    **use** Illuminate\Http\Request;
    
    **class** FileUploadsHelper
    {
    **public function** uploadVideo($file, $folder, $file_prefix, $max_width = **false**)
    {
        // 构建存储的文件夹规则，值如：uploads/images/video/201709/21/
        // 文件夹切割能让查找效率更高。
        $folder_name = "uploads/$folder/" . date("Y/m/d", time());
    
        // 文件具体存储的物理路径，`public_path()` 获取的是 `public` 文件夹的物理路径。
        // 值如：/home/vagrant/Code/changan/public/uploads/video/201709/21/
        $upload_path = public_path() . '/' . $folder_name;
