以下是使用封裝類，可直接使用：

<?php

namespace libraries\apk;


class Apk
{

    /**
     * 前提：安裝PHP ZIP擴展
     * 擴展下載：https://windows.php.net/downloads/pecl/releases/zip/
     * 查看zip是否安裝成功：phpinfo() 搜索zip -> Zip	enabled 即可用
     * desc：讀取APK
     * author：wh
     * @param string $path
     */
    function read(string $path){
        /*解析安卓apk包中的壓縮XML文件，還原和讀取XML內容

        依賴功能：需要PHP的ZIP包函數支持。*/

        $appObj = new ApkParser();

        $targetFile = $path;//a.apk; apk所在的路徑地址

        $appObj->open($targetFile);//$res

        return [
            'app_name'=>$appObj->getAppName(),// 應用名稱
            'package'=>$appObj->getPackage(),// 應用包名
            'version_name'=>$appObj->getVersionName(),// 版本名稱
            'version_code'=>$appObj->getVersionCode(),// 版本代碼
        ];
    }
}

重要提示：安裝擴展！安裝擴展！安裝擴展！
