请帮帮我！我正在使用此代码生成apk或jar缩略图。如apk.php
<?php
include('vvv.php');
$file = $_GET["lf"];
$q = array("res/drawable-mdpi/icon.png","res/drawable/ic_launcher.png","res/drawable/ic.png","res/drawable/appicon.png","res/ drawable/icon.png","res/drawable-hdpi/icon.png","res/drawable- hdpi/ic_launcher.png","res/drawable-hdpi/appicon.png","res/drawable-hdpi/ic.png","res/drawable- mdpi/ic_launcher.png","res/drawable-mdpi/ic.png","res/drawable-mdpi/appicon.png","res/drawable- ldpi/ic_launcher.png","res/drawable-ldpi/ic.png","res/drawable-ldpi/icon.png","res/drawable- ldpi/icon.png","res/drawable-ldpi/appicon.png","res/drawable-xhdpi/ic_launcher.png","res/drawable- xhdpi/ic.png","res/drawable-xhdpi/icon.png","res/drawable-xhdpi/ot_ic_launcher.png","res/drawable- xhdpi/appicon.png","res/drawable-xxhdpi/ic_launcher.png","res/drawable-xxhdpi/ic.png","res/drawable- xxhdpi/icon.png","res/drawable-xxhdpi/appicon.png","res/drawable- nodpi/fk_icon_96.png","res/drawable-hdpi/ic_app.png","res/drawable- hdpi/widget_icon.png","res/drawable-mdpi/icon_zdevicetest.png","res/drawable- mdpi/app_icon_my_own.png","res/drawable/app_icon.png","res/drawable- hdpi/icon_green.png","res/drawable- hdpi/jb_smsmms.png","res/drawable/ic_launcher_wallpaper.png","res/drawable- hdpi/theme_icon.png","res/drawable/theme_icon.png","res/drawable- nodpi/icon.png","res/drawable/board.jpg");
$name = $setup['tpath'].'/'.basename($file).'.gif';
$apk = new PclZip($file);
$a = $apk->extract(PCLZIP_OPT_BY_NAME,$q,PCLZIP_OPT_EXTRACT_IN_OUTPUT);
if(!empty($a)) {Header("Content-type: zipdata/png");}
else { Header("Content-type: ext/jar.png"); }
?>
并且工作正常，它会生成一个像
这样的网址http://example.com/apk.php?lf=path/to/file/filename.apk&id=fileid
但它并没有将拇指保存到像其他拇指脚本一样的文件夹中。
所以请帮我把拇指保存到服务器上的文件夹中！
$ q也定义了apk文件图标的路径。
