这段时间太忙了，一个月没有写博客了，稍微闲下来就感觉把在开发中遇到的问题记录下来

php上传安卓apk包的时候，需要获取安卓apk包内的信息

<?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
class ApkParser{

        try {
          return $this->parseString($xml);
        }catch (Exception $e){
        }
      }
    }
    return false;
  }
 
  public function parseString($xml){
    $this->xml = $xml;

    $xml .= $node['tag'];
    $this->line = @$node['line'];
    foreach ($node['child'] as $c){
      $xml .= $this->getXML($c, $lv+1);
    }
    return $xml;
