/**
* This class manage upload, with use of the JUpload applet. It's both a sample to show how to use the applet, and
* a class you can use directly into your own application.
*
* Recommandation: Don't update its code !
*
* By doing this, you'll be able to reuse directly any update coming from the JUpload project, instead of reporting your
* modifications into any new version of this class. This guarantees you that your project can use the last version of
* JUpload, without any code modification. We work so that the applet behavior remains unchanged, but from time to time,
* a change can appear.
*
* Sample:
* - See the index.php samples, in the same folder.
*
* Notes:
* - maxChunkSize: this class use a default maxChunkSize of 500K (or less, depending on the script max size). This allows
* upload of FILES OF ANY SIZE on quite all ISP hosting. If it's too big for you (the max upload size of your ISP is less
* than 500K), or if you want no chunk at all, you can, of course, override this default value.
*
*
*
* Parameters:
* - $appletparams contains a map for applet parameters: key is the applet parameter name. The value is the value to transmit
* to the applet. See the applet documentation for information on all applet parameters.
* - $classparams contains the parameter specific for the JUpload class below. Here are the main class parameters:
* - demo_mode. Files are uploaded to the server, but not stored on its hard drive. That is: you can simulate the global
* behavior, but won't consume hard drive space. This mode is used on sourceforge web site.
*
*
* Output generated for uploaded files:
* - $files is an array of array. This can be managed by (a) the function given in the callbackAfterUploadManagement class
* parameter, or (b) within the page whose URL is given in the afterUploadURL applet parameter, or (c) you can Extend the
* class and redeclare defaultAfterUploadManagement() to your needs.
* See the defaultAfterUploadManagement() for a sample on howto manage this array.
*
* This array contains:
* - One entry per file. Each entry is an array, that contains all files properties, stored as $key=>$value.
* The available keys are:
* - name: the filename, as it is now stored on the system.
* - size: the file size
* - path: the absolute path, where the file has been stored.
* - fullName: the canonical file name (i.e. including the absolute path)
* - md5sum: the md5sum of the file, if further control is needed.
* - mimetype: the calculated mime type of the file
* - If the formData applet parameter is used: all attributes (key and value) uploaded by the applet, are put here,
* repeated for each file.
*
* Note: if you are using a callback function (i.e. callbackAfterUploadManagement) and you do not see a global 'object' you
* are expecting then it might have been destroyed by PHP - c.f. http://bugs.php.net/bug.php?id=39693
