[2003-09-30] A Dynamic PHP Thumbnail Gallery Part 2
Welcome back to part two of the Code Gallery Spotlight of the PHP based Photo Gallery called "AutoGallery". Last week, I discussed with you the general idea of the AutoGallery's image management and introduced the constructor used to initialize the variables in the AutoGallery class. This week, I'll take a look at the two functions that the constructor calls after initialization resize() and cleanup() and how they perform the necessary management of the gallery images. Let's start with the resize() function.

In my last column, I introduced the resize() function and a simple cache system is used to create and keep updated the thumbnails for all the images that are to be displayed in the picture gallery. This week, I'll introduce the second half of the AutoGallery's management system by discussing the checkup() member function which handles the removal of thumbnails which are no longer necessary.
[2003-09-29] Websites Require Flexible Not Fixed Design
A website needs to be flexible. It needs to be able to change as the organization changes. The more change within the organization the more flexible the website needs to be. Too many websites are still being designed from a print perspective; as if they were some once-off brochure.

Today I'll be starting a new series focusing on the use of PHP's image manipulation functions to create a sharp-looking web based photo gallery. If you have been working with PHP for any reasonable length of time (or for that matter, really looked at our own Code Gallery) you'll notice that there have been many different types of PHP scripts focused on creating "thumbnail" images. This week's spotlight takes that concept a few steps further and includes some great features like multiple-gallery support, the addition of a border around your thumbnails, and a gallery indexing system used to speed up the web page as a whole.

The Widget Queen Revisited You have the world's finest collection of widgets. You created the world's best widget website. You have no traffic. You checked in the search engines and find that your site does not appear at all, even though all your competitors' sites do. Perhaps the search engine robots cannot get to your pages to index them. Search Engine Robots Search engine robots are simple creatures. They can "read" text to add to their databases, and they can follow "normal" links--those links that are coded to look like <a href="bluewidgets.html">blue widgets </a> or the slight variation <a href="bluewidgets.html ><img src="bluewidget.gif" ></a>
[2003-09-17] Five Habits for Successful Regular Expressions
Regular expressions are hard to write, hard to read, and hard to maintain. Plus, they are often wrong, matching unexpected text and missing valid text. The problem stems from the power and expressiveness of regular expressions. Each metacharacter packs power and nuance, making code impossible to decipher without resorting to mental gymnastics.
[2003-09-08] Site Design: Think The Way Your Customer Thinks
One of the biggest challenges an organization faces is to stop thinking it's the center of the universe. Customers think that they are the center of the universe. Customers come to your website to get their needs fulfilled. They will only think you are great if you meet their needs in an efficient and cost-effective manner.
[2003-09-03] Getting Your Web Site Listed in the Google Index
Reader Question: I have submitted my site to the major search engines including Google and DMOZ (Open Directory Project). I'm not getting much traffic to my site and believe this is largely because the site can't be found on Google. We've used the proper meta tags, meta-description and header bar, even the home page body is keyword rich. I've been busy getting links to the site from other relevant sites.
