Introduction: This tutorial is on how to list data from a MySQL table. HTML: Before we begin, we are going to create some basic HTML code to correctly format our information we will be listing later.

Introduction: This tutorial will be on allowing users to input data in to an HTML form, and then upload that data to a MySQL database through PHP. HTML: First we need our HTML form. This example will just be for a user to enter their username and email address, we will not do any validation or username checking (to assure no duplicate usernames within our website) as this is not the purpose of this tutorial.

Introduction: This tutorial is on how to use encryption to transfer data securely, or at least more seucrely than plain text, from a Visual Basic application (or other source) to a PHP API. Why Cryptography? Cryptography should be used for all sensitive information being used in public release applications, or if the data is sent cross-networks.

Introduction This tutorial is on using MD5 encryption in PHP. Why MD5? MD5 is built in to PHP and is only a one way encryption. This means that even if someone was able to gain access to an encrypted md5 string, called an 'MD5 Hash', it is unlikely they would be able to convert the hash back in to the original plain text string. Decryption: Decryption in most cryptography languages essentially work by using the reverse algorithm to the encryption algorithm used by the cryptography method in question.

Introduction: This tutorial is on how to upload POST data to a PHP file on a web server or localhost through Visual Basic .NET. Why POST? POST is the method used to upload sensitive data such as passwords, as opposed to using the PHP GET method which will simply show all data in the URL bar; GET - http://www.website.com/page.php?password=ThisIsMyGETPassword POST - http://www.website.com/page.php Both example sites would receive the same information, but the POST one is undercover and therefore slightly more secure. Why Only Slightly More Secure?

Introduction: This tutorial is on how to process data through the GET type in PHP.
