Building an advertising system with PHP, Part 1

(Page 1 out of 3)


Most of us who run websites will most likely want to add advertising on our websites some time in the future. The easiest way to do this is to simply take the advertising code (be it HTML or JavaScript), and paste it directly into the code of our HTML. But what if we eventually get multiple advertisers for the same spot? In the beginning this is unlikely, but as your website grows and becomes more popular, it's to be expected that you will have accommodate for multiple advertisers.

In that case you must use some sort of advertising management script. The best one around, phpAdsNew, is completely free and can be downloaded at, but this might be slightly overkill for most websites, since phpAdsNew is a complete ad management application, packed with features you probably won't need anyway. Why don't we create our own simple advertising system?

In this article, the first part of a new three part series, I will show you how to build your own advertising system. In this first part I will take you through the basics of dynamic JavaScript, and how to serve multiple advertisements in the same spot. Let's get started.

Dynamic JavaScript using PHP

The easiest way to serve different advertisements is to use an external JavaScript file, e.g.

                </span>Demo 1<span class="sc2"><span class="kw2">


        src="ads.js" type="text/javascript">


The ads.js file can insert any content using document.write (or by adding new elements to the DOM). This means we can use JavaScript to serve different ad's in the same spot, but why do all the backend work in JS, when we've got PHP to work with?

First of all, point the script tag to a PHP file, like this:

                </span>Demo 1<span class="sc2"><span class="kw2">


        src="js1.php" type="text/javascript">


Then paste the following in js1.php:

$time = date("g:i:s A", mktime());
header ("Content-Type: text/javascript");
echo "document.write ('The time is now $time');";

This simple example demonstrates that it's possible to use JS and PHP together to add dynamic content. The js1.php uses JS to output extra content, with can contain anything.

Let's have a look at creating a really bare-bones advertising system now.
