DevShed: Getting PHP to Talk to MySQL [2007-05-19 21:01:16] DevShed is getting back down to some of the basics with this new tutorial - the first part of a three-part series looking at connecting PHP with a MySQL database backend. The article is part of an excerpt from the O'Reily book "Learning PHP and MySQL" (by Michele Davis and Jon Phillips). In this first part of a three-part series. you will begin learning how to use PHP to display and modify data from a MySQL database. They step through the process of connecting to the database server, picking the database you want to work with, creating a SELECT statement for the data in the tables, running it and getting back the information. For this first part of the series, though, they only go as far as making the connection including the solution to one of the most common errors people experience - the "call to undefined function" problem.

WebReference.com: Security Techniques [2007-05-14 11:35:11] Filed under their "Advanced Topics" sections today is a new article from WebReference.com that looks at some security techniques developers can use in their apps to help keep their and their user's information safe from prying eyes. It's an excerpt from Larry Ullman's book "PHP 5 Advanced: Visual QuickPro Guide". + This chapter will begin by rehashing the fundamentals of secure PHP programming. These are the basic things that I hope/assume you're already doing. After that a quick example shows ways to validate different kinds of data that might come from an HTML form. + The third topic is the new-to-PHP 5 PECL library called Filter. Its usage isn't very programmer-friendly, but the way it wraps all of the customary data filtering and sanitizing methods into one interface makes it worth knowing. After that, two different uses of the PEAR Auth package show an alternative way to implement authorization in your Web applications. The chapter will conclude with coverage of the MCrypt library, demonstrating how to encrypt and decrypt data. The security tips in this part of the series range from turning off register_globals (you do have it off, don't you?) to form validation with things like regular expressions and the ctype functions.

PHPBuilder.com: Securing Data Sent Via GET Requests [2007-05-11 09:16:05] On PHPBuilder.com today, there's a new tutorial that talks about a method to securing data sent via GET requests in your application. In this article I'm going to show you how you can use PHP to encode your data for transit. Most importantly, it will be done in a way that makes the data decodable, and therefore much more usable, by the receiving page. They talk about some of the advantages to encryption before getting into how it actually works. Their example script is separated out into three PHP files - the main part of the script, a single-use script that, in turn, creates the third file, include file for the encode/decode functions. With the structure defined, they move on to the code - the generation of the file with the large multi-dimensional array and the two functions to encode and decode the information.

DevShed: Implementing the Stage Pattern in PHP 5 [2007-04-19 19:19:49] Back with another of their design patterns articles, DevShed looks this time at the Stage pattern - a flexible pattern that allows your application to adapt to requests. At least at first glance, the definition of the "Stage" pattern seems hard to grasp, which implies that the pattern in question has to be addressed from a practical point of view. In doing so, you'll have a much better idea of how it works, and eventually how it can be applied in concrete cases. [...] Over the course of this two-part series, I'm going to introduce its key concepts, and logically show you how to implement it with copious code samples. They start by defining a DIV class to act as a foundation for the Stage functionality (with methods to set the ID, the CSS class and the data inside it). They also develop a DivContext class to handle special methods surrounding the inputted DIV. Bringing it all together, they create a default DIV object and pass it into the custom DivContext to get and set the contents of the DIV.
