The initial script in the first tutorial of this series lacked some important features, such as the implementation of an effective error handling module and the ability to check the MIME type and size of the file being uploaded. In this second installment of the series, I'm going to improve the logic of the script from the first tutorial to provide it with the capacity to retrieve useful information concerning the entire file uploading process.

They look back at the previous tutorial to remind you of some of the concepts and then move on to show you how to get information about the file (like the MIME type, name and size of the uploaded file). The last page is just the full source code for the cut and pasters out there.

Since in the first part of the series I showed you how to create a proxy class for processing simple XML strings, in this installment I'm going to teach you how to create a proxy object that can be used in conjunction with the "DirectoryIterator" class that comes with PHP 5.

They start with the definition of a proxy class, the base to start from, and improve its functionality through additional methods like getSize, getPath, and getTimeStamps (using the iterators). The complete the development by pulling the parts together and creating a final example that loops through a given path and displays various info about the directory/files inside (size, names, timestamp, etc).
