I’ve been too busy during this period. I haven’t blogged for a month. When I have some free time, I feel like recording down the problems I encountered during development

When php uploads the Android apk package, it needs to obtain the information in the Android apk package

<?<span style="color: #000000;">php

</span><span style="color: #008000;">/*</span><span style="color: #008000;">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。</span><span style="color: #008000;">*/</span>

<span style="color: #0000ff;">include</span>('./Apkparser.php'<span style="color: #000000;">);

</span><span style="color: #800080;">$appObj</span>    = <span style="color: #0000ff;">new</span><span style="color: #000000;"> Apkparser(); 

</span><span style="color: #800080;">$targetFile</span> = a.apk;<span style="color: #008000;">//</span><span style="color: #008000;">apk所在的路径地址</span>

<span style="color: #800080;">$res</span>     = <span style="color: #800080;">$appObj</span>->open(<span style="color: #800080;">$targetFile</span><span style="color: #000000;">);

</span><span style="color: #800080;">$appObj</span>->getAppName();         <span style="color: #008000;">//</span><span style="color: #008000;"> 应用名称</span>

<span style="color: #800080;">$appObj</span>->getPackage();        <span style="color: #008000;">//</span><span style="color: #008000;"> 应用包名</span>

<span style="color: #800080;">$appObj</span>->getVersionName();    <span style="color: #008000;">//</span><span style="color: #008000;"> 版本名称</span>

<span style="color: #800080;">$appObj</span>->getVersionCode();    <span style="color: #008000;">//</span><span style="color: #008000;"> 版本代码</span>
?>
Copy after login

The following is the Apkparser class package. Copy the following code and save it as Apkparser.php to execute the above code
