Prior to beginning this discussion forum, read Chapter 13: PHP Classes and Objects from the course textbook, and review thePredefined Variables: $_FilesLinks to an external site.web page, which addresses file upload variables and superglobals. Superglobals are specially-defined array variables in PHP that make it easy for you to get information about a request or its context. Superglobals were introduced in PHP 4.1.0, and they can be accessed from any function regardless of scope.
For your initial post,
Determine which superglobal function can be used to send files from client browsers to the web server.
Describe the process on how you can send files to the server.
Provide the code you created to develop the upload functionality.
Explain what the first thing you should do—as a web developer—to handle the file after you upload it to the server.
Complete the order form by providing as much information as possible, and then click the submit button.
