PHP5 includes a built-in SQLite extension that allows you to store data in a database without a standalone database server! Say good-bye to the pesky accompanying MySQL database server that you had to run alongside PHP. SQLite can help you to make your applications more portable, to avoid pesky file-based storage, and more! In this article, Matt goes through the basics you need to get started using SQLite in your PHP applications today!

I'm nearing the time when I need to start benchmarking the code of a project I'm working on and I have been browsing around the web for some various tips on optimising PHP code. So far I've come across a few fairly authoritative-looking lists with up to 63 different tips for optimising PHP code (one of which is the original list with a number of new tips added). The best formatted list is at PHP Bench; however, it's a fairly limited sample. The lists at Reinhold Weber's website and Chazzucka contain significantly more tips, but don't provide…

Awhile ago, I found a nice web development website called Smashing Magazine. The vast majority of their content consists of top 10, top 50, and top 100 lists of information and tools that are of interest to web designers. Most of these lists are generally not of interest to me; however, one of them really stood out as being a useful list that I could use. The list is of their top 50 PHP tools, ranging from debugging tools to PHP frameworks, is particularly useful. One of my favourite tools that is listed is one that I've just began using ca…

As Matt said in his last blog post, both Matt and I are making predictions about what will happen in 2009 with technology and web development. We'll revisit both our posts at the end of next year to see who was right and who was wrong! Make sure to read Matt's post for his predictions too. OpenID Prediction: OpenID will officially die out and lose all hope of being adopted as a widespread standard. Matt predicted that OpenID would become a login method on more mainstream websites, but still lack mainstream use. My prediction is simi…

Coding an All-in-one RSS Feed

One of the cool new things that we have added at Lowter recently is an all-in-one RSS feed that contains both our articles and our blog entries. Granted, the feed doesn't contain "all" of Lowter's content, such as new forum threads and blog comments, but it is very encompassing nonetheless. Coding such an all-in-one RSS feed is pretty easy! First, I'm going to assume that you want to make a combined feed of both your articles and blog entries. You can easily change the code to fit whatever combining scenario you have, such as different so…

POST vs. GET

When I first started learning web development, I had a hard time understanding the differences between the two HTTP request methods POST and GET. Some of the early Lowter members will remember an issue with only being able to post forum posts under 2000 characters, which was a result of me accidently using GET to submit the user's posts. Matt actually spotted the issue and probably wanted to reach through the computer screen and slap me for such a naïve error. Alas, I've come quite a ways since then. Now, there is a lot of technical …

PHP: Determining MIME Type
- Author

PHP lacks a definite way to detect the MIME type of a file across each PHP version. Older versions of PHP use the mime_content_type() function, whereas more recent versions encourage the use of the Fileinfo set of functions. These variations present a difficulty when developing an application that must work across multiple versions and installations of PHP. In order to solve this problem, I use the following code to create a function to check the MIME type of a file regardless of the development environment: <?php // Setup replaceme…

Useful Function: Multiple-dimension Array Search

Awhile back I found that I really needed a way to search through multi-dimensional arrays. PHP has the in_array() function built-in to the language, but I needed a similar function that would search through an array with more than one dimension. I use the following function in_array_multiple() to get this job done and it works perfectly. It is a very simple function, but it does exactly what it needs to: <?php /** * Multiple-dimensional array search * * @param string $needle Value searching for * @param array $haystack Array…

If you have ever picked up a book or visited a website about design patterns, it is almost certain the examples in those resources are in Java. However, Doug on the forums posted a link to the website Patterns for PHP, which focuses on design patterns in PHP. Currently they have articles on a good selection of design patterns: Singleton Registry Factory Abstract Factory Strategy Composite Decorator Lazy Initialisation Transfer Object For the most part these are the design patterns that people will use the most.

Zend has released the first official version of the Zend Framework for PHP. For those who do not know, one of the common criticisms of PHP is that there is no de-facto framework for PHP. The Zend Framework has been predicted to fill this void. The framework is more like a set of tools, such as the .Net framework. It is not a framework like Ruby on Rails or CakePHP. I have not had much experience using the Zend Framework yet, but I will in the near future.…

Templating engines are a great asset to any application or website maintained by a development team. It helps to separate design logic and presentation into two sections. This allows the developers to maintain the program and pass the final values to a template. Then the designers and webmasters can easily change the presentation without having to deal with any code. Many developers use the Smarty template engine. While Smarty offers a nice amount of features that really take templating far and beyond, it is slightly bloated. PHP itself…

In this entry I will discuss how to use content negotiation to your advantage and offer the correct mime-type for your code to the browsers which can handle it. Last year, I only used to check the HTTP_ACCEPT header of a browser for the presence of application/xhtml+xml, which can be done easily by using: <?php if (stristr($_SERVER, 'application/xhtml+xml')) { } ?> However, conversations with others showed me that this is not the right way to do this, because if a browser adds a q value to the HTTP_ACCEPT header (like …
