PHP Error Checking

“Just when you think you've made something foolproof, God makes a better brand of fool.” This maxim of manufacturing also applies to software development, especially on a highly accessible technology like web applications. As much as programmers attempt to anticipate every possible action or combination of actions that a user can take when encountering a web application, no one can foresee them all. When the user takes an unanticipated course of action and “breaks” the application, the...

5 PHP Security Measures

For many years, PHP has been a stable, inexpensive platform on which to operate web-based applications. Like most web-based platforms, PHP is vulnerable to external attacks. Developers, database architects and system administrators should take precautions before deploying PHP applications to a live server.

JavaScript And Recursion

Recursion is an age old concept used in mathematics when an object is defined by other objects of the same type.  A real life example would be the mirrors in a department store dressing room. If you look in the right spot, you can see both reflections repeating themselves in each other.  Each iteration of your image grows smaller and smaller into infinity. In computer science recursion happens when a solution to a problem is resolved by computing smaller instances of the same problem.  In JavaScript,...

In our last session, we finished writing the PHP class file that would control all the ad banner functions.  This week, we look at the presentation layer for the administration of these functions. The ads_list.php page lists the current banner ads.  First, we must include the class file so that the page can instantiate the class call the functions: <?php require_once("class.ads.php"); // instantiate ads class $oAds = new ads; Next, we fill the $aAds array with the data from the ads table and get...

Pushing Updates to the Web Page with HTML5 Server-Sent Events

The HTML5 Server-Sent event model allows you to push realtime data updates from the server to the browser. In this tutorial we will work through the process, with the EventSource object handling received data and writing it to the page. We will use HTML5 and JavaScript at client side, with PHP at server side. With existing models such as AJAX, the code in a Web page would continually ask the server to supply new data, but the onus was on the client to request the information. With Server-Sent requests, you...
