一，extend目录的功能:

      extend目录可以存放自己所开发的具备通用功能的类，        vendor目录存放的是通过composer下载的第三方库        注意与app目录下的内容区分

二，编写php代码:

1,controller/Article.php

<?php
declare (strict_types = 1);
 
namespace app\controller;
 
use app\BaseController;
use zip\zip;
 
class Article extends BaseController
{
    //生成zip文件
    public function zip() {
        $pathArr = [
            "/var/www/html/goodsimage/orig/61e7c3a0327ad.gif",
            "/var/www/html/goodsimage/orig/gsl.jpeg",
        ];
        $zipName = "/var/www/html/goodsimage/image.zip";
        $zip = new zip();
        $res =$zip->makeZip($pathArr,$zipName);
        //if ($res['code'])
        echo $res['code'];
        exit;
    }
}

2,extend/zip/zip.php

<?php
namespace zip;
 
class zip {
    //打包一个zip文件
    public function makeZip($pathArr,$zipName) {
        $zip = new \ZipArchive();
        if($zip->open($zipName,\ZipArchive::CREATE|\ZipArchive::OVERWRITE)){
            foreach($pathArr as $file){
                if(!file_exists($file)){
                    continue;
                }
                //向压缩包中添加文件
                $zip->addFile($file,basename($file));
            }
            $zip->close();
            return ['code'=>0,'msg'=>"创建成功",'path'=>$zipName];
        }else{
            return ['code'=>1,'msg'=>'创建失败'];
        }
    }
}

三，测试效果

1,访问:

http://192.168.219.6:8000/article/zip

返回: 2,查看生成的zip包:

四，查看php和thinkphp的版本:
