这篇文章主要介绍了php获取apk包信息的方法,非常实用的功能,需要的朋友可以参考下,有时候在使用php上传安卓apk包的时候,我们需要获取安卓apk包内的信息,本文以实例形式讲述了php获取apk包信息的方法。具体实现方法如下:
- <?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。
- <?php
- //-------------------------------
- //Apkparser类包开始
