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：
open($targetfile);$appobj->getappname();// 应用名称$appobj->getpackage(); // 应用包名$appobj->getversionname(); // 版本名称$appobj->getversioncode(); // 版本代码?>
以下是apkparser类包，把以下代码复制出来保存为apkparser.php就可以执行以上代码
open($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) ?
