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  = 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//-------------------------------class ApkParser{//----------------------// 公共函数,供外部调用//----------------------  public function open($apk_file, $xml_file='AndroidManifest.xml'){    $zip = new /ZipArchive;    if ($zip->open($apk_file) === TRUE) {      $xml = $zip->getFromName($xml_file);      $zip->close();      if ($xml){        try {          return $this->parseString($xml);        }catch (Exception $e){        }      }    }    return false;  }  public function parseString($xml){    $this->xml = $xml;    $this->length = strlen($xml);    $this->root = $this->parseBlock(self::AXML_FILE);    return true;  }  public function getXML($node=NULL, $lv=-1){    if ($lv == -1) $node = $this->root;    if (!$node) return '';    if ($node['type'] == self::END_TAG) $lv--;    $xml = @($node['line'] == 0 || $node['line'] == $this->line) ?
