Introducing Session Management Php, Mysql Part-l

A session manages the interaction between a web browser and a web server. For example, a session allows an application to track the items in a shopping cart, the status of a customer account application process, whether or not a user is logged in, or the finalizing of an order. Sessions are essential to most web database applications.

A session has two components: session variables and a session identifier (ID). The session variables are the state information that's related to a user's interaction with an application. For example, the session variables might store that the user's shopping cart contains five items, what those items are, their price, what items the user has viewed, and that the user is logged into the application. The session variables are stored at the web server or database server, and are located using the session ID.

When a session is started, the user's browser is given a session ID. This ID is then included with subsequent requests to the server. When a browser makes a request, the server uses the session ID to locate the corresponding session variables, and the variables are read or written as required. In practice, session variables are typically stored at the web server in a file (the PHP default) or at the database server in a table. 

Shows how the session variables for Beth's session are identified and stored in the web server environment; the session ID distinguishes between Beth's session and other users of the system.

Using sessions, all of the variables that represent the state of an application don't need to be transmitted over the Web. The session ID is transmitted between the browser and server with each HTTP request and response, but the session data itself is stored at the server. The session ID is therefore like the ticket given at a cloakroom. The ticket is much easier to carry around and ensures that you get back your own hat and coat. Storing variables at the server also helps prevent accidental or intentional tampering with state information.

The session ID is usually transmitted as a cookie . A cookie is a named piece of text that is stored in a web browser, and is sent with HTTP requests, like data sent with the GET or POST methods. You can find out more about cookies from the interesting Cookie Central web site at http://www.cookiecentral.com/faq/ or more formally in RFC 2109 at http://ietf.org/rfc/rfc2109.txt?number=2109.

At A Glance: ASP.net vs. PHP

In the world of web development, the choice of which development language to use commonly comes down to two popular choices. Web applications, specifically those relying on back end databases, are typically being created using either Microsoft's ASP.Net language, or the Open Source alternative language of PHP. Reasons why one might choose one over the other can include: The cost of development tools, or availability of such tools, or even ones comfort level with the Open Source initiative. The goal of this article is to provide some perspective on reasons why one might choose one over the other.

Active Server Pages or ASP has long been an option for creating dynamic web content. Active Server Pages facilitates the ability to use databases such as Access or SQL just to name a few, to create dynamic, feature rich websites. The work going on behind the scenes in serving up the dynamic content is being done at the server level by the Active Server Pages source code. Microsoft has spent a great deal of time and resources promoting their .Net family of programming languages of which ASP.Net is a member.

In order to develop with ASP.Net one must obtain the extremely expensive Microsoft Visual Studio Programming Suite. While expensive, Visual Studio is an asset to any programmer due to its vast amount of features. As with all of Microsoft's products, support and updates are constantly made available for ASP.Net. The shear amount of features that Microsoft packs into Visual Studio, coupled with Microsoft's extensive support make certainly make ASP.Net an attractive solution for any corporation's web development needs, but the cost can be prohibitive, if not impossible to afford for the individual web developer.

PHP which is in its 5th revision now, is an Open Source web development language that also facilitates the creation of feature rich, dynamic websites that can use databases. Being Open Source means simply that PHP isn't owned by anyone. Just as with Active Server Pages, the work going on behind the scenes of serving up the dynamic web content is being done by PHP at the server level. As with most Open Source products, the resources available to a PHP developer are free of charge.

This makes PHP extremely attractive to the independent web developer. There are some commercial quality development suites available from companies like Zend, but there is also wealth of free resources just a Google Search away. Because there is really no corporate entity behind PHP, support and development on PHP is done by the community of its users and developers themselves.

Surprisingly this does not seem to adversely affect the ability to find support for PHP. All in all, ASP.Net and PHP are both excellent options, offering basically the same functionality. Whether the decision comes down to the cost of initial investment, or the comfort level one has regarding Open Source, or something else entirely, the end result depends upon the mastery of whichever language is chosen.

PHPBB2 is a terrific bit of open source software. Build the forum the way you want and then select the "mods" that work the best for you.

the program is free and with a little help from the PHPBB community, not impossible to install even for the novice. The program you will upload, however, is fairly basic in nature therefore modifications [or, mods as some prefer to call them] can be useful to install. I have found several favorites that have worked rather well for me. Now, I am plan on sharing that information with you!

Chat – What forum isn’t complete without a chat room. PHPBB2, for one. Yes, you have to install one yourself but the IRQ chat add-on is certainly worth it and it works much better than some that I have seen on sites that contain this feature. EZBoard is one such site that comes to mind.

Who Is Online – As an administrator you already know who is online at any given time. Unfortunately, the “stock” version of this feature shows people who have been online only for the past five minutes. Fortunately, a mod has been developed that can extend this feature to fifteen minutes or later. Is this important? No, but it gives you a more accurate picture of what your real time traffic figures really are.

Google Ads – A special mod has been developed to permit you to run and display banner ads, much like Google’s AdSense. Hey, you want to make a little bit of money off of your site now don’t you?

Smilies – You do love emoticons, don’t you? Well even if you don’t, they can certainly spice up any forum. Lots of neat “paks” have been developed, some containing animated icons too. Especially nice to have around Yuletide for easy access to Christmas themed emoticons.

Disable Board Message – Being able to customize the message you have posted when your site is down is essential to clueing in your members as to the time when your forum will once again become activated. This mod does just that.

There are numerous other mods and styles from which you can choose. Some are easy to install while others are moderately so. A small group of mods are difficult to install and will take you well over one hour to complete. Choose your battles wisely and be careful when you install updates to PHPBB2. By not selecting a “patch” file update you can erase any modifications you made in just moments.
