Sometimes when using php to upload Android apk package, we need to obtain the information in Android apk package. This paper tells the method of php obtaining apk package information in the form of examples. The specific implementation method is as follows:
<?php
/* Analyze Android apk Compression in a package XML File, Restore, and Read XML Content
Dependent functionality: Required PHP Adj. ZIP Package function support. */
include('./Apkparser.php');
$appObj = new Apkparser();
$targetFile = a.apk;//apk The path address where it is located
$res = $appObj->open($targetFile);
$appObj->getAppName(); // Application name
$appObj->getPackage(); // Application package name
$appObj->getVersionName(); // Version name
$appObj->getVersionCode(); // Version code
?>
The following is the Apkparser class package, which can be executed by copying the following code and saving it as Apkparser. php
<?php
//-------------------------------
//Apkparser Class package start

//----------------------
// Public function for external call
