Description

DownloadUtil is a utils class which allow you to securly download data from other websites.

what is the use of this plugin ?

When people are developping modules, they often need to download data from other server. In order to do that, there is a simple way with the function "fopen" and the directive "<tt class="parameter">allow_url_fopen". But this directive is evil, as it can allow hackers to download files from others servers and eventually to execute php code. The effect are even worst , if the directive "<tt class="parameter">allow_url_include" is activated. Indeed, people could include file from others servers.

With the developpement of hack as a business (look for botnet on google for details), lot of hack attempt happens everyday on your website, on an average website, you can hava 6000 hack attempt a week (try bad behavior to see the result on your site), this is not something that you can not consider in the creation of a website.

This class allow you to download data with curl, eventually if "curl" extension is not found, it will use "<tt class="parameter">allow_url_fopen" as a workaround. As most of the code was already in zikula (thumbnail module), you can just consider this class as a shortcut for easiily downloading data.

How to use it ?

I want to download a picture to a given file ...

Loader::loadClass("DownloadUtil",".");
$url_img="http://community.zikula.org/themes/community/images/logo.gif";
$fileName = FileUtil::generateRandomFilename(7,10,true,false,false).".temp";
        $isOk = DownloadUtil::getToFile($url_img,$fileName);
        if ($isOk ){
            // do stuff
        }

I want to download a remote text file(for instance a txt file with the current version name of your module in order to advice people for update)

Loader::loadClass("DownloadUtil",".");
$url="http://www.isi.edu/in-notes/rfc1591.txt";
$data = DownloadUtil::get($url);
echo $data;

Notes : thumbnail module is required , as it's holding the phpthumb library
