PHP FILE DETAILS MOD
There are several different types of credit cards that one can use to make a purchase, however they can all be validated using the Mod 10 algorithm.Īs well as passing the Mod 10 algorithm, a credit card number must also pass several different formatting rules. This algorithm processes some simple numerical data validation routines against the number, and the result of this algorithm can be used to determine whether or not a credit card number is valid. What do we actually mean when we say "validate a credit card number"? Quite simply it means that we run a credit card number through a special algorithm known as the Mod 10 algorithm. To implement the class we’ll create in this article, you should have access to an Apache web server running PHP 4.1.0 or later. In this article we’re going to work through the development of a PHP class that stores the details of a credit card and validates its number using the Mod 10 algorithm. Before you actually encrypt your customer’s credit card numbers to a database or forward them to a merchant server, it’s a good idea to implement your own credit card validation routine. Move_uploaded_file($file_tmp,"images/".Although online payment options such as PayPal have become extremely popular in the last couple of years, the majority of online stores still use some sort of merchant system to accept credit card payments from their Websites.

So if the value assigned to the input's name attribute in uploading form was file, then PHP would create following five variables − This variable is an associate double dimension array and keeps all the information related to uploaded file. There is one global PHP variable called $_FILES. It will produce the following result − Creating an upload script Move_uploaded_file($file_tmp,"images/".$file_name)

The PHP script that was specified as the form handler in the form's action attribute checks that the file has arrived and then copies the file into an intended directory. The selected file is sent to the temporary directory on the server.
