Understanding Upload Process
Before we start building our application, I think it's a good idea for us to understand how is the upload process working. First thing we should remember that in the html forms for uploading files, we should type enctype=multipart/form-data. With that property of a form, we told the browser to prepare the given file to be uploaded to the server to be processed.
Next, when web user selects a file on his local computer or network drive then he clicks the submit button, the file is uploaded to the temporary directory on the server with a random name. Now what the script does is grab that file from temporary directory and put it anywhere you want. You can use copy() or move_uploaded_file() or any other function that you would like. On this sample that we will discuss here we are going to put that file into a database.
