SitePoint PHP Blog:
Rapid Development of Zend Expressive Modules
Sep 07, 2017 @ 11:49:43

The SitePoint PHP blog has a new post from Kirk Madera sharing some of the things he's learned about creating modules in Zend Expressive. His goal is to make it as easy as possible and enable "rapid development" in your application. This is the second part of a series on rapid development with Zend Expressive from Kirk (part one is here).

I have learned a few tricks when writing Zend Expressive modules that I want to share with you.

Please follow the previous post first to set up a proper working environment. I explained how to install and configure Zend Expressive with Doctrine, Gulp, and an abstract reflection factory – it’ll take a total of 10 minutes.

In this tutorial, we’ll build a simple read-only blog module (a page listing blog posts from a database) in minutes, demonstrating the kind of rapid development one is capable of with Zend Expressive.

He then shows how to use the command line tooling to create the module and how it is registered with Composer. He then shows the creation of the "blog" entity and database tables followed by the routing changes. Next he fleshes out the actions that will respond to the requests on each route and the templates that will be served as a part of the response.

Rob Allen:
Deploying a PHP application to Cloud Foundry
Aug 30, 2017 @ 10:22:03

Rob Allen has a new post to his site today showing you how to deploy your PHP application to Cloud Foundry, an open source cloud platform that helps to automate deployment onto multiple cloud infrastructures.

I recently had a requirement to deploy a Slim application somewhere. As I already have a Bluemix account, it seemed sensible to deploy it to their Application Runtimes service which is an installation of the Open Source Cloud Foundry project.

This turned out to be quite easy, but there are a number of steps involved, so I'm documenting it here.

After installing some of the command line tools he then prepares the PHP application by selecting a version, creating a manifest file, setting up buildpack options and defining rewrite rules. He then walks you through the deployment steps required to push the code out to the Bluemix host via Cloud Foundry, including the commands needed to make it all work.

SitePoint PHP Blog:
Rapid Enterprise App Development with Zend Expressive
Aug 29, 2017 @ 15:41:34

The SitePoint PHP blog has posted a new tutorial from author Kirk Madera showing you how to use Zend Expressive to aid in more rapid development in your applications.

If you’ve ever done a Zend Framework quick start, you’ve probably never worked in Zend Framework. The quick start has historically been anything but quick, and it’s easy to lose interest and move on to the next thing.

Zend Expressive greatly improves upon this experience with the wizard driven composer create-project command. However, it can still be daunting to set up because there are so many choices to make up front. This tutorial guides you through my recommended setup for rapid development which will yield an enterprise level, robust application.

He then walks you through the creation of a Zend Expressive project from scratch and how to ensure it's up and running as expected. He then walks you through the structure of the application, software it includes (like Doctrine and Gulp) and examples of them in use. The post ends with a look at creating console commands using the Symfony Console component.

Marco Bunge:
Application logic done right
Aug 14, 2017 @ 12:13:13

In a recent post to his site Marco Bunge offers some suggestions on how to write good application logic in a "clean, testable and reusable" way.

Web based enterprise applications are often accessible via different user interfaces through protocols like HTTP, Sockets, RPC, CLI. The Model-View-Controller is still present as a user-interface pattern. But requests and responses needs to be handled in the way of their interface requirements.

We don’t want to write the same logic for each required interfaces. Furthermore we don’t want to test and maintain code for each required interfaces. We want to write, test and maintain reusable source code at a central point of the application eco-system.

He then talks about the ideas behind the "three-teir architecture" and how this structure can be used to split logic into layers: presentation, logic and data. He mentions domain driven design as a development method to help achieve this structure and his meaning of the word "clean". He then gets into the implementation of this structure, defining the major pieces of functionality for each tier (with code for each included). He ends the post with some suggestions of points for additional reading about things like presenters, the ADR pattern and the "Inversion of Control" principle.

Matt Stauffer:
What packages do you install on every Laravel application you create?
Jul 19, 2017 @ 12:29:44

On his site Matt Stauffer has a post that asks the readers about the packages they always install for their Laravel applications (and not necessarily just Laravel related packages either).

In preparation for my upcoming [talk](http://customlaravel.com/) at [Laracon 2017](https://laracon.us/), which I'm titling "Custom Laravel," I [asked a quick question](https://twitter.com/stauffermatt/status/885666786036899840) on Twitter to my followers. [...] I wanted to know for my talk, but I was also just curious for my own purposes. Are there any packages I should check out that everyone else already knows about? Here's what I found, in order of the number of recommendations I received...

While most of the packages in his lists (unanimous support, well-loved, etc) are Laravel specific, mostly because of his audience on Twitter, there are some that weren't. These included:

You can check out his full listing in the remainder of the post and a link to another listing from Mike Erickson asking the same kind of question.

Freek Van der Herten:
Optimize images in Laravel apps
Jul 17, 2017 @ 09:48:01

In a continuation of his previous post about an image optimization package for PHP Freek Van der Herten covers some refactoring and advancements they've made to the package to make it even easier to use.

A while ago we released image-optimizer. In short this package can make all kinds of images smaller by stripping out metadata and applying a little bit of compression. Read this blogpost to learn more about it. Although it’s pretty easy to work with the package, we felt that we could deliver a more seamless experience in Laravel apps. That’s why we created our newly released laravel-image-optimizer package.

The package uses a bunch of binaries to optimize images. To learn which ones and how to install them, head over to the optimization tools section in the readme of the underlying image-optimizer package. That readme also contains info on <a href="https://github.com/spatie/image-optimizer#which-tools-will-do-what>what these tools will do to your images.

He then includes some code examples putting this new version of the package to work with a Laravel-based application. The examples include replacing the image with an optimized one, saving the optimized one to a new path and resize all images in a request. There's also an example configuration included showing the options you can set to customize your site's image optimization even more.

Laravel News:
A guide for prioritizing application errors
Jul 03, 2017 @ 10:17:26

The Laravel News site has posted a tutorial that offers some advice on how to prioritize fixing bugs and errors in your applications.

One major problem is that prioritizing errors isn’t always clear. Figuring out how much negative impact a bug is really causing is important to answer because not all bugs are worth fixing.

That’s why having a solid workflow in place for prioritizing bugs is so important. In order to confidently allocate your engineering resources on bug fixes and feature building, you need to understand the scope of each application error, and its impact on your customers. Then you can definitively say particular bugs are high enough priority that they should be scheduled into a sprint alongside your work on building new features.

The article is then broken down into a few different sections, each with a few points underneath:

  • Get setup with smart error reporting from the start
  • Focus your error inbox to keep it actionable
  • Prioritize the most relevant errors first
  • Prioritize errors by moving them into your debugging workflow

The post is sponsored by Bugsnag so there's some of the content that suggests using their service but the advice is sound for any kind of error handling workflow.

Olav van Schie:
Make your Laravel App Fly with PHP OPcache
Jun 14, 2017 @ 10:16:21

On his Medium site Olav van Schie shows you how to "make your Laravel app fly" with the help of OPcache. While OPcache isn't something that's specific to Laravel, he does include a package near the end that makes it easier to use it with the caching built into "artisan".

Every time you execute a PHP script, the script needs to be compiled to byte code. OPcache leverages a cache for this bytecode, so the next time the same script is requested, it doesn’t have to recompile it. This can save some precious execution time, and thus make your app faster (and maybe save some server costs).

He starts with a brief overview of OPcache and the main benefit it provides. He also shares some benchmarks he performed on a Digital Ocean server based on the results of performance testing the default Laravel "welcome" page. He then shows how to check and be sure it's installed and enabled on your PHP installation and some good default settings to configure in your php.ini. The post wraps up mentioning the package that helps integrate it with the Laravel application and the command required to clear out the OPcache on deploy.

Stephan Hochdöfer:
Dockerizing GitLab Review Apps
Jun 07, 2017 @ 10:28:15

On the BitExpert blog Stephan Hochdöfer has written up a post showing how to "Dockerize" GitLab review apps to create a consistent platform for these self-contained environments.

Last year GitLab introduced the Review Apps feature. Review Apps are app environments that are created dynamically every time you push a new branch up to GitLab. As a bonus point the app environments are automatically deleted when the branch is deleted. Since we moved to using docker for quite a few of our projects I was keen on figuring out how to combine Docker and the GitLab Review Apps functionality as the documentation only mentions NGINX as a way to run Review Apps. As it turns out, it is rather simple to deploy docker containers as a Review App.

He describes the environment he needs and which tools he'll be using to perform the build of the environments. He then defines the sample GitLab configuration file including the "build" stage. He briefly explains the steps this follows then shows the configuration for the "deploy" step, grabbing the latest image from his Docker repo and running it. He ends the post with an "undeploy" stage that removes the Docker build automatically when the environment is no longer needed.

SitePoint PHP Blog:
How to Build a Twitter Follower-Farmer Detection App with RestDB
May 31, 2017 @ 12:17:03

The SitePoint PHP blog has a tutorial posted for the Twitter users out there showing you how to create a "follower-farmer" detection tool that will scan your account for followers that track your account and then soon after unfollow as a means of gaming the follower system.

Are you active on Twitter? If so, do you often wonder why some accounts seem to follow you only to unfollow you moments (or days) later? It’s probably not something you said – they’re just follower farming.

[...] Follower farming is a known social media hack taking advantage of people who “#followback” as soon as someone follows them. [...] In this post, we’ll build an app which lets you log in via Twitter, grabs your followers, and compares the last fetched follower list with a refreshed list in order to identify the new unfollowers and calculate the duration of their follow, potentially auto-identifying the farmers.

They use a Homestead VM and a fresh Laravel installation to create their application. It makes use of the Socialite package to connect to Twitter using your application's client ID and secret. The application then makes use of the guzzlehttp/oauth-subscriber package to connect to the Twitter API and get a list of current followers. The post also includes the code to create a "FollowerServiceProvider" to make it simpler to get the follower information. He then shows how to set up the RestDB account and push the follower content out to it for storage. The tutorial wraps up with the code required to analyze the followers against "unfollowers" and report back the results.
