Php method for obtaining apk package information

This article mainly introduces the php method for obtaining apk package information, which is very useful. if you need it, you can refer to the following: Sometimes when using php to upload an Android apk package, we need to obtain information in the Android apk package. This article describes how to obtain the apk package information by php in the form of an instance. The specific implementation method is as follows:

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. Copy the following code and save it as Apkparser. php to execute the above code.

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-> roo T; if (! $ Node) return ''; if ($ node ['type'] = self: END_TAG) $ lv --; $ xml = @ ($ node ['line'] = 0 | $ node ['line'] = $ this-> line )?
