How to Install Community PHP on IBM i

Now that community PHP is available for IBM i, you may be wondering how to set up the open source operating system on the platform. Unlike the single-step install (RSTLICPGM) that delivers a certified PHP stack as part of Zend Server setup, community PHP requires installation and configuration of multiple packages.

4 Reasons to Use Image Processing to Optimize Website Media – SitePoint PHP

4 Reasons to Use Image Processing to Optimize Website Media

This sponsored article was created by our content partner, BAW Media. Thank you for supporting the partners who make SitePoint possible.

Image optimization is a big deal when it comes to website performance. You might be wondering if you’re covering all the bases by simply keeping file size in check. In fact, there’s a lot to consider if you truly want to optimize your site’s images.

Fortunately, there are image processing tools and content delivery networks (CDNs) available that can handle all the complexities of image optimization. Ultimately, these services can save you time and resources, while also covering more than one aspect of optimization.

In this article, we’ll take a look at the impact image optimization can have on site performance. We’ll also go over some standard approaches to the problem, and explore some more advanced image processing options. Let’s get started!

Why Skimping on Image Optimization Can Be a Performance Killer

If you decide not to optimize your images, you’re essentially tying a very heavy weight to all of your media elements. All that extra weight can drag your site down a lot. Fortunately, optimizing your images trims away the unnecessary data your images might be carrying around.

If you’re not sure how your website is currently performing, you can use an online tool to get an overview.

Results of a website speed test

Once you have a better picture of what elements on your website are lagging or dragging you down, there are a number of ways you can tackle image optimization specifically, including:

  • Choosing appropriate image formats. There are a number of image formats to choose from, and they each have their strengths and weaknesses. In general, it’s best to stick with JPEGs for photographic images. For graphic design elements, on the other hand, PNGs are typically superior to GIFs. Additionally, new image formats such as Google’s WebP have promising applications, which we’ll discuss in more detail later on.
  • Maximizing compression type. When it comes to compression, the goal is to get each image to its smallest “weight” without losing too much quality. There are two kinds of compression that can do that: “lossy” and “lossless”. A lossy image will look similar to the original, but with some decrease in quality, whereas a lossless image is nearly indistinguishable from the original but also heavier.
  • Designing with the image size in mind. If you’re working with images that need to display in a variety of sizes, it’s best to provide all the sizes you’ll need. If your site has to resize them on the fly, that can negatively impact speeds.
  • Exploring delivery networks. CDNs can be a solution to more resource-heavy approaches for managing media files. A CDN can handle all of your image content, and respond to a variety of situations to deliver the best and most optimized files.

As with any technical solution, you’ll have to weigh the pros and cons of each approach. However, it’s also worth noting that these more traditional approaches aren’t the only options you have available to you.

Xdebug Update: December 2019 – Derick Rethans

Xdebug Update: December 2019

Another month, another monthly update where I explain what happened with Xdebug development in this past month. It will be published on the first Tuesday after the 5th of each month. Patreon supporters will get it earlier, on the first of each month. You can become a patron here to support my work on Xdebug. If you are leading a team or company, then it is also possible to support Xdebug through a subscription.

In December, I worked on Xdebug for near 50 hours, on the following things:

Xdebug 2.9.0

After releasing Xdebug 2.8.1, which I mentioned in last month’s update, at the start of the month, more users noticed that although I had improved code coverage speed compared to Xdebug 2.8.0, it was still annoyingly slow. Nikita Popov, one of the PHP developers, provided me with a new idea on how to approach trying to find out which classes and functions still had to be analysed. He mentioned that classes and functions are always added to the end of the class/function tables, and that they are never removed either. This resulted in a patch, where the algorithm to find out whether a class/function still needs to be analysed changed from from O(n²) to approximately O(n). You can read more about this in the article that I wrote about it. A few other issues were addressed in Xdebug 2.9.0 as well.

Breakpoint Resolving

In the May update I wrote about resolving breakpoints. This feature will try to make sure that whenever you set a breakpoint, Xdebug makes sure that it also breaks. However, there are currently two issues with this: 1. breaks happen more often than expected, and 2. the algorithm to find lines is really slow. I am addressing both these problems by using a similar trick to the one Nikita suggested for speeding up code coverage analysis. This work requires quite a bit of rewrites of the breakpoint resolving function, and hence this is ongoing. I expect this to cumulate in an Xdebug 2.9.1 release during January.

debugclient and DBGp Proxy

I have wanted to learn Go for a while, and in order to get my feet wet I started implementing Xdebug’s bundled debugclient in Go, and at the same time create a library to handle the DBGp protocol.

The main reason why a rewrite is useful, is that the debugclient as bundled with Xdebug no longer seems to work with libedit any more. This makes using debugclient really annoying, as I can’t simply use the up and down arrows to scroll through my command history. I primarily use the debugclient to test the DBGp protocol, without an IDE “in the way”.

The reason to write a DGBp library is that there are several implementations of a DBGp proxy. It is unclear as to whether they actually implement the protocol, or just do something that “works”. I will try to make the DBGp proxy that I will be working on stick to the protocol exactly, which might require changes to IDEs who implement it against an non compliant one (Komodo’s pydbgpproxy seems to be one of these).

This code is currently not yet open source, mostly because I am still finding my feet with Go. I expect to release parts of this on the way to Xdebug 3.0.
