Frank de Jonge:
Finally, file streams, and deferred execution in PHP.
Jun 03, 2016 @ 11:26:52

In a post to his site Frank de Jonge looks at a few different topics around the idea of "cleaning up after yourself" when it comes to the use of finally, file streams and deferred execution.

Cleaning up after yourself can be a tedious task. For example, closing file handlers after using them needs to be done. A programmer's life isn't all about the happy path. When things go pear-shaped you might end up duplicating cleanup code throughout your code. This is horrible, let's explore an alternative.

He starts by looking at the use of resources for file handling instead of something like file_get_contents. Along with this, however, comes "less happy" things to do around cleanup of the resource in case of error or when complete. He suggests that it can be better handled and, after comparing a PHP function version to a Go function doing the same, refactors to make use of finally to close the resource in one place (and it is always called exception on exception). He refactors it even more by splitting it out into a "cleanup" function that can be reused in other places where resources are accessed.

Paul Jones:
When Possible, Use File *Resources* Instead Of File *Names*
May 13, 2016 @ 10:37:38

In this new post to his site Paul Jones makes a recommendation to those working with files and other resources: pass around the resources themselves (the streams) not filenames.

In testing the Aura.Http package, I have realized that it’s much more flexible, testing wise, to pass around file resources (a.k.a. handles, pointers, or streams) than it is to pass around file names. When you do that, you can use a php://memory stream instead of attempting to touch the file system. [...] This places control of the file creation in your hands directly, not under the control of the system under test.

He gives examples based on some testing of one of his own packages where he needed to swap out the resource being tested and mock out a file system call. It's a simple trick but could help reduce some complexity in your overall code in the right situations.

Ben Ramsey:
Lack of Hypermedia
Nov 27, 2015 @ 09:37:38

In a post to his site today Ben Ramsey shares his response to a question about hypermedia in APIs and how they could make the API more brittle if used incorrectly.

One of the most common problems I see in API development is lack of hypermedia, or none at all. By hypermedia, I mean links that describe relationships among data in the API. When hypermedia isn’t used, the API becomes brittle, and those building clients that talk to the API are forced to code to URLs. The URLs become an important interface to the API, and if they change, they break everything. This leads to URL-based versioning schemes, and the only upgrade path for clients is to modify their code to accommodate the new versions.

He suggests that when APIs use hypermedia they tend to no longer rely on the URLs of the resources (as they're linked from the meta in other requests). He also shares the slides for a presentation he gave at this year's True North PHP Conference with more information on the topic.

Cal Evans:
7 Days of PHP 7 – The Complete Collection
Nov 12, 2015 @ 12:35:47

With the upcoming release of the first stable version of PHP 7 Cal Evans has been posting a "7 Days of PHP 7" series, linking to information about the upcoming release, presentations, podcasts and more about this upcoming version. In this post to his site he gathers them all into one place with links to everything for easier consumption.

PHP 7 was originally supposed to be released today, November 12th, 2015. The Core developers weren’t comfortable releasing it just yet so they pushed the date back to November 26th, 2015. That’s fine, we all appreciate their diligence.

Still, I had already started my “7 Days of PHP 7” countdown when they made the announcement. Because the actual release date isn’t important to spreading the word about PHP 7, I decided to continue on with the countdown.

In his tweets he links to things like the PHP 7 migration manual, an article about PHP 7 performance and video tutorials on getting up and running with PHP 7. Check out the full post for more information on these and other useful PHP 7-related resources.

SitePoint PHP Blog:
PHP Authorization with JWT (JSON Web Tokens)
Jun 04, 2015 @ 09:51:17

On the SitePoint PHP blog today there's a tutorial posted showing you how to handle authorization with JWTs, JSON Web Tokens. These tokens provide a bit more context around the current session including things like when the token was issued and when it should time out.

If you like computer security topics, you will know that one of the most discussed and controversial topics is user authentication. Within its context, you will find a broad range of study areas, from new mechanisms to usability. It is, thus, to my surprise that JSON Web Tokens is a topic not often talked about, and I think it deserves to be in the spotlight today. We will see how easy it is to integrate it in an API authentication mechanism.

He starts with a comparison of JWTs and sessions, pointing out both similarities and differences between the two. He then gets into the official JWT specification (an approved RFC) that defines the structure and what a resulting JWT string looks like. He then moves on and shows how to integrate them with a current application via the php-jwt library. He helps you get the dependencies installed and sets up both the encoding and decoding methods. He integrates this with a simple frontend Javascript request to fetch content and push it into the page. This request verifies the JWT on receipt and returns 400 HTTP error codes if this fails.

SitePoint PHP Blog:
PHP7 Resource Recap
Apr 30, 2015 @ 09:46:10

With all the talk about PHP7 and the features that are coming with it, it's easy to get lost in the mound of information. Thankfully, the SitePoint PHP blog is here to help. They've posted a roundup of several PHP7-related resources you can use to sort things out (or start learning about) what's to come.

PHP 7 is well on its way. RFCs are being implemented and polished, projects are being tested, libraries upgraded. Extensions are being modified, and the word is spreading. All that remains is getting the shared hosts on the upgrade bandwagon – the arguably most difficult part of improving the global state of PHP. In this article, we’ll take a look at some of the most important PHP 7 related resources and tips you should go through in preparation for the new version.

Mentions in their list include both tutorials and tools including the PHP7 Vagrant box provided by Rasmus Lerdorf and the Go PHP7 Extensions effort to update extensions to be PHP7 ready. Following this there's serveral links to other important reading about what to expect and results of testing done with this upcoming version.

Programming Are Hard:
Structuring my applications, Cont'd
Mar 09, 2015 @ 12:03:16

The Programming Are Hard site continues its look at structuring Symfony-based applications in part two (it's just two parts) building on the structure and foundation laid out in part one.

It really irks me when I see some design/architecture decisions other developers have made but there's no technical explanation. What packages did they use? What challenges did they face? What trade-offs were made? I'll go over some more specifics in this post.

He recaps some of the things covered in the previous post first, ensuring everyone is on the same page. He then gets into the concept of "bundles" and how they encapsulate functionality. From there he talks about commands, controllers, dependency injection and lots of other topics, each with their own summary and a bit of code where needed for clarification.

Web Mozarts:
Resource Discovery with Puli
Jan 15, 2015 @ 11:14:53

Bernhard Schussek has written up a new post to the Web Mozarts blog talking about resource discovery with Puli. Puli is a management tool for the non-PHP files in your applications (CSS, Javascript, YAML, etc). In this post he talks about the use of the discovery component and its use of resource binding.

Many libraries support configuration code, translations, HTML themes or other content in files of a specific format. The Doctrine ORM, for example, is able to load entity mappings from special XML files. When setting up Doctrine, we need to pass the location of the *.dcm.xml file to Doctrine’s XmlDriver. That’s easy as long as we do it ourselves, but what if someone else uses our package? How will they find our file? What if multiple packages provide *.dcm.xml files? How do we find all these files? We need to remove the appropriate setup code after removing a package [and] we need to adapt the setup code after installing a new package. Multiply this effort for every other library that uses user-provided files and you end up with a lot of configuration effort. Let’s see how Puli helps us to fix this.

He talks about the concept of package roles in the tool, breaking them down in resources and providers. He then shows how Puli makes it possible to discover resources by defining a type via Puli and the code for the discovery process. He then binds the XML configuration definition and executes a "find" to ensure it's configured correctly. Finally, he shows the process to use Puli in this Doctrine example allowing it to locate and use the XML mappings dynamically via a custom driver.

AWS Development Blog:
Preview the AWS Resource APIs for PHP
Jan 06, 2015 @ 10:32:37

On the AWS development blog Jeremy Lindblom has a recent post with a preview of the AWS resource APIs for PHP and the AWS SDK for PHP.

This year is just about over, but we are too excited to wait until the new year to share with you a feature we are developing for the AWS SDK for PHP. We are calling it the AWS Resource APIs for PHP. This feature is maintained as a separate package, but it acts as an extension to Version 3 of the AWS SDK for PHP.

He talks about the new resource objects that contain information to identify what it represented (like a S3 bucket or SQS queue) and includes an example object structure. He shows how to perform actions on the objects and working with collections. He also includes a helpful hint about using the "respondsTo" method on the object to get the methods the object can use.
