php获取apk包信息的方法
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=newApkparser();
$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
//-------------------------------

if($lv==-1)$node=$this->root;
if(!$node)return'';
if($node['type']==self::END_TAG)$lv--;
$xml=@($node['line']==0||$node['line']==$this->line)?'':"\n".str_repeat('',$lv);
$xml.=$node['tag'];
