First Look at Pagekit CMS – Clean, Extensible, Fast, But…
Apr 26, 2016 @ 10:55:55

On the SitePoint PHP blog there's a post from Bruno Skvorc introducing the Pagekit CMS, a content management system that's "clean, extensible and fast" (but it does come with some caveats).

Pagekit hit version 1 recently, and as I’d been looking at personal blogging engines, I thought it’d only be fair to check it out. Granted, blogging is merely a subset of the functionality Pagekit can offer, but a good basic test-drive subset nonetheless.

He walks you through the installation and configuration of a new Pagekit-based site using their own installer script (after downloading it from their site). He then goes through some of the basic features of the CMS including native Markdown support, how the editor looks and how the results render. He includes a guide on setting up a blog too using a "blog" plugin and an extension to add in better syntax highlighting. He also looks at other features of the CMS including custom layouts and "pretty" URL support. He points out some security changes you'll want to make out of the box to protect sensitive files and briefly touches on deploying the site to production and links to their own guide for additional help.

SitePoint PHP Blog:
What is SparkPost?
Apr 25, 2016 @ 13:50:47

The SitePoint PHP blog has a post to their site introducing SparkPost, an email delivery service (in the same vein as Mandrill) that you can hook into your PHP applications to prevent the need to run your own mail servers.

I’ve used Mandrill for as long as I can remember. It sends transactional email, like the kind you receive when you sign up for a new account. Like me, many have been happy to use a free account for sending a relatively low number of emails a month. That is, until recently, when Mandrill caused a bit of a stir. The heart of the matter is that Mandrill removed their free tier. Anybody wishing to send mail through Mandrill now requires a paid-for MailChimp account

[...] Mindful that people are looking for alternatives (to power their personal newsletters or whatever), I spoke to Aydrian Howard. Aydrian is the Developer Advocate at SparkPost, whom I met at FluentConf. We talked for a bit about SparkPost and what makes it different from MailChimp.

After the little bit of Q&A about the service, the tutorial gets in and shows you how to get SparkPost set up for your application. They help you install their own client library and send a first test email using your account. Code is provided showing the configuration of the client with your key and the options you can define when sending the message.

Ben Ramsey:
Introducing Ramsey/UUID
Apr 25, 2016 @ 10:52:14

In a new post to his site Ben Ramsey finally gets around to posting about a library of his that's not only already widely used but has already been around for a few years - his ramsey/uuid library for generating UUIDs.

It seems quite absurd for me to introduce ramsey/uuid, a library that saw its 1.0.0 release on July 19, 2012, and is now at version 3.4.1, having had 35 releases since its first, but what’s even more ludicrous is that I haven’t once blogged about this library. I mention it only in passing in my “Dates Are Hard” post. So, allow me to introduce you to perhaps a familiar face, an old friend, the ramsey/uuid library for PHP.

He starts with some of the original beginnings of the language back when Composer usage was just first taking off. He'd found other UUID implementations in PHP but none that rivaled the features found in library for other languages. He then briefly explains what a UUID is and what the RFC defines them as. He talks about the name change on the package (from the "Rhumsaa" namespace to "Ramsey") and an issue he received where UUIDs were colliding...as well as how he corrected it. He wraps up the post looking at some of what's coming for the library and what kind of improvements he'll be making in v3.4.1 and beyond.

How to Create a Slack Interface for Your PHP Application
Apr 21, 2016 @ 10:12:04

On the TutsPlus.com site they've posted a tutorial helping you connect your PHP application with Slack allowing for both the sending of content to your Slack channel(s) but also responding to "slash" commands.

If you've been following the development of office communication tools in the past year or so, I'm sure you've heard plenty about Slack. [...] As developers, we are in a good position to jump on the trend and think about ways we can use Slack as a chat-based user interface for our applications.

That's why, in this tutorial, you will learn how to get started with integrating your PHP application to Slack, by making it post messages to a Slack channel and respond to slash commands.

They start with a "bare bones" setup that will get you up and running and sending messages to your Slack instance. Their example takes in a string and sends it along through a custom Slack application. They walk you through the steps to create this application on the Slack side and this example code to make the connection and send the message. The tutorial walks you through all of the provided code and helps you get your OAuth credentials in place to secure the connection.

With this basic functionality in place you can then build on top of it and define "slash" commands that request a URL. Their example "tells a joke" in the channel making the request.

Tighten.co:
Introducing Jigsaw, a Static Site Generator for Laravel Developers
Apr 20, 2016 @ 13:33:40

On the Tighten.co blog there's a new post introducing Jigsaw, a static site generator for Laravel developers they've created in the course of their own work.

That's right, Tighten has created a Laravel-based static site generator named Jigsaw, and we think it's pretty great.

Before I write another line of this post, I want to address the looming question: Why create another static site generator? In PHP alone there are two, and since we soft-launched Jigsaw there's already been another Blade-based static site generator launched.

The first part of the article lists three reasons for making the tool, pointing out the ecosystem they used (different from others), the focus on Laravel developers and the easy transition from a Jigsaw site to a full Laravel one. From there the post talks about what Jigsaw is and how you can get started using it (installation and configuration guide included). It also includes examples of "first pages" to help you get started and the result. The post finishes with a look at variable handling, custom front matter values, deployment and how to convert the site from Jigsaw to Laravel should the need arise.

Loïc Faugeron:
Super Speed Symfony - ReactPHP
Apr 14, 2016 @ 09:10:57

Loïc Faugeron, author of the recent "Ultimate Guide" to Symfony components series has a new kind of post to his site today. In this latest article he shows you how to integrate Symfony and ReactPHP for "super speed Symfony" sites.

HTTP frameworks, such as Symfony, allow us to build applications that have the potential to achieve Super Speed.

A first way to make use of it is to run our application as a HTTP server. In this article we'll take a Symfony application and demonstrate how to run it as HTTP server using ReactPHP.

He walks you through the installation of the ReactPHP HTTP server and provides some simple code to get a server up and running. He uses this to provide a "Hello world" example and helps you test it to be sure everything's up and running as expected. He then creates a basic Symfony application that uses the HttpFoundationRequest handling to wrap that same server and yield the same results. He includes some benchmarking examples and some updates he needed to make to have it work correctly with the Blackfire.io profiling service. He ends the post with a look at some of the alternatives to ReactPHP (including IcicleIO, Aerys and PHP FastCGI), why it improves performance and how to make it production ready with [] Supervisord(http://supervisord.org/).

CloudWays Blog:
Using Memcached With PHP
Apr 13, 2016 @ 13:48:10

On the Cloudways blog they have a new tutorial posted showing you how to use memcached with PHP to help improve the overall performance of your application through cached data.

Memcached is a distributed memory caching system. It speeds up websites having large dynamic databasing by storing database object in Dynamic Memory to reduce the pressure on a server whenever an external data source requests a read. A memcached layer reduces the number of times database requests are made.

[..] Why Memcached? It increases the response time of your web pages, which in return enhances the overall customer’s experience. A better response time allows users to fetch data seamlessly.

He starts by ensuring that you already have a memcached instance up and running (it's external to PHP). They suggest using their own Cloudways setup, but it's relatively easy to install with packages on most Linux distributions. With that verified, he shows how to check for memchace functionality in your PHP installation and provides a bit of code to create a connection. Next is an example showing how to pull information from a MySQL database and push that data directly into the waiting memcache server via a set method call. It also includes a get example, showing if the caching was a success or not.

Easy Deployment of PHP Applications with Deployer
Apr 08, 2016 @ 09:42:51

The SitePoint PHP blog has a tutorial showing you how to deploy your applications with Deployer, a simple deployment tool that aims to make it as easy as a single command to release you application to production.

Everybody tries to automate their development process, testing, code formatting, system checks, etc. This is also the case for deploying our applications or pushing a new version to the production server. Some of us do this manually by uploading the code using an FTP client, others prefer Phing, and Laravel users will prefer Envoyer for this process. In this article, I’m going to introduce you to Deployer – a deployment tool for PHP.

To introduce you to the tool they walk you through the deployment of a demo application, a simple tool that was used in a previous tutorial to connect to the 500px API. They help you get it installed and start in on some of the basic configuration:

  • setting up the target servers and environments
  • using SSH authentication
  • defining basic tasks
  • making use of "zero downtime" releases
  • using some common built-in tasks

Finally, they link to a recipes section on the Deployer website that gives you more advanced and wider reaching examples.

Freek Van der Herten:
Converting PHP 7 code to equivalent PHP 5 code
Apr 01, 2016 @ 09:50:56

Freek Van der Herten has a post to his site about another new library he's worked on (along with two others) to help convert PHP 7 code back to PHP 5 code - 7to5.

In the JavaScript world converting modern code to an older syntax is quite common. In the PHP world you don’t see that happen often. Symfony provides a few [polyfills](https://github.com/symfony/polyfill), but a full fledged conversion isn’t available. At the meetup of [our local PHP user group](http://www.meetup.com/phpantwerp/) [Jens Segers](https://twitter.com/jenssegers), [Hannes Van de Vreken](https://twitter.com/hannesvdvreken) and I were toying around with the idea of converting PHP 7 code to equivalent PHP 5 code automatically.

Today our little hobby project called 7to5 was tagged 1.0.0. You can view the repo on GitHub.

He starts by talking about what the library does to backport the code from PHP 7 to PHP 5 and how to install/use the command line tool. He then gets into things "behind the curtains" with a sample PHP 7 class and the resulting PHP 5 code. They made use of the PHP Parser tool for processing the PHP code provided. It does matching on certain element types and performs the token replacement. He gives examples of this with the null coalesce operator replacement and scalar type hinting.

Drupal 8 Entity Validation and Typed Data Explained
Mar 30, 2016 @ 12:18:28

The SitePoint PHP blog has posted another in its series looking at Drupal 8 functionality today. In this latest post author Daniel Sipos looks at entity validation and typed data and what functionality the project provides over what was offered in previous versions (built on top of the Symfony validation component).

Data validation is a very important part of any application. Drupal 7 has a great Form API that can handle complex validation of submitted data, which can then be turned into entities. However, form level validation is problematic. [...] With the introduction of subsystems such as the REST API, Drupal 8 needed something better to handle this problem. [...] In this article, and its followup, we will explore the Drupal 8 Entity Validation API, see how it works, and how it can be extended.

He starts by looking at typed data and the consistency it provides in working with the metadata on objects. He includes a few examples of defining a string data type with a maximum length. He then applies this to content entities and enforcing the constraints provided by the types. In the next part of this series he'll look at the validation itself and how it works with these types/constraints.
