<?php/*解析安卓apk包中的压缩XML文件，还原和读取XML内容依赖功能：需要PHP的ZIP包函数支持。*/include('./Apkparser.php');$appObj = new Apkparser(); $targetFile = a.apk;//apk所在的路径地址$res = $appObj->open($targetFile);$appObj->getAppName(); // 应用名称$appObj->getPackage(); // 应用包名$appObj->getVersionName(); // 版本名称$appObj->getVersionCode(); // 版本代码?> |
以下是Apkparser类包，把以下代码复制出来保存为Apkparser.php就可以执行以上代码
