Build A Simple Chat With ReactPHP Socket: Server
Jun 28, 2017 @ 10:46:39

Sergey Zhuk has a new post to his site showing how you can use ReactPHP's socket component to build a simple chat service as a server runing on a remote port.

In this article, we are going to build a simple chat server based on ReactPHP Socket Component. With this component, we can build simple async, streaming plaintext TCP/IP or a secure TLS socket server.

There are client and server sockets. The server is bound to a specific port number and just waits listening on this port. The client knows the host of the server and the port on which the server is listening. When the connection between server and client is established, the data exchange begins.

He then gets into the code required to make the server and add in some additional functionality. He starts by creating the server to listen for incoming connections and has it write back a simple message to prove it's working correctly. He then moves on to the code required for sending and receiving data. This initial version just echoes back what the user submits. He takes this an expands it out to start on the intiial steps of the chat system - creating the connection pool for multiple clients, storing usernames of those connected and using that information when transmitting a message to all clients connected.

Create A Contact Form In Laravel That Sends You An Email
Jun 23, 2017 @ 11:17:02

On the Cloudways blog they've posted a tutorial showing you how to create a simple contact form that emails when someone fills it out and the information they submitted.

Laravel is well known for providing multiple solutions for a problem. This is one of the main reasons of the popularity of the framework. Popular Laravel solutions cover routine functionality such as authentication, sessions, routing, and caching.

Contact Us forms are another routine functionality that is a requirement of more or less every website. In this article, I am going to demonstrate how you can easily create a contact form in Laravel with email. To understand the functionality of Laravel mail function. I suggest you read my previous article on sending emails in Laravel.

The author then walks you through the installation of a new Laravel application on the Cloudways service. He then shows how to install the "Form" package (laravelcollective/html) and enable it as a service provider. Next up comes the database configuration and the creation of the table to handle the data submitted via the "Contact Us" form. The model is then created to work with the table, the route is added to show the form (and handle the submission) as well as the matching view and controller. The post wraps up with the commands and configuration you'll need to send the emails and an example of a "mailable" class to handle the email's construction.

Dynamic Page Templates in WordPress, Part 3
Jun 19, 2017 @ 10:45:04

The TutsPlus.com site has posted the third part of their "Dynamic Page Templates in WordPress" tutorial series today. In this latest article author David Gwyer finishes off the series using all that they've shared from part one and part two to create two examples.

In the first two parts of this tutorial series, we covered what dynamic page templates were and why they were needed. We also looked at the code required to implement them.

In this third and final tutorial in the series, I'll be creating two examples of fully working dynamic page templates you can use in your own projects. These were specifically chosen to be easily extendable to suit your own needs, and are intended as inspiration for any other type of dynamic page templates you can think of.

He then walks you through the creation of the two page templates: a Simple Contact Form and a Blog Post Archive. The first allows you to dynamically control the form elements for a UI interface (rather than code) and the second uses dynamic data to display the list of previous blog posts. The tutorial then finishes with a look at how, since WordPress 4.7, you can use dynamic page templates with any kind of post, not just pages.

May 30, 2017 @ 10:25:45

On the Laravel News site they've introduced a package from Adam Wathan that cam help simplify the use of the popular Guzzle package for making HTTP requests. Zhttp is a wrapper around Guzzle and tries to make the code to make the requests simpler and easier to follow.

Zttp is a new PHP package by Adam Wathan that is a Guzzle wrapper designed to bring an expressive syntax and simplify common use cases. [...] Zttp simplifies the code to make the request and automatically returns the JSON response.

A few other examples of requests using the tool are provided: POSTing with parameters, sending a PATCH/PUT request, adding an Accept header and how to prevent the request from following redirects. You can find out more on the project's GitHub repository and grab the latest release to try out in your own code.

Dac Chartrand:
Building a Simple API using Opulence PHP
Jan 30, 2017 @ 11:27:35

Dac Chartrand has written up a post to his site showing you how to create a simple REST API with Opulence, a PHP framework that bills itself as a "modern framework for modern PHP".

This tutorial will show you how to code a simple JSON API using Opulence PHP. We will install Opulence’s skeleton project using composer, then create a ‘user’ database entity, and finally we will match CRUD (Create, Read, Update, Delete) to POST, GET, PUT, and DELETE.

The start of the tutorial helps you get a new Opulence project set up and running including updating the configuration for content type handling and the database connection details. With that set up he moves into the code creating the "User" entity and its matching classes. He builds out the controller, selecting a REST controller from the options and builds out all methods needed for the CRUD user operations. The tutorial finishes with a bit of testing information so you can see the framework in action.

Jason McCreary:
Update PHP on Mac OS X
Sep 20, 2016 @ 10:15:26

Jason McCreary has posted an update to his guide for installing PHP on Mac OS X and replacing the version of PHP that comes with El Capitan (5.5) with a handy package manager more specific to PHP installations.

As noted in my posts on Installing Apache, PHP and MySQL on Mac OS X, OS X comes pre-installed with Apache and PHP. Unfortunately, as of Mac OS X 10.11 (El Capitan) the pre-installed version of PHP is still 5.5. As PHP 5.5 has reached end of life, I imagine the pre-installed version of PHP will be updated with Mac OS 10.12 (Sierra). However, it may only be PHP 5.6.

So what do you do if you want to upgrade or install a different PHP version on your Mac? Well, you could use Homebrew. But I found a pre-packaged alternative - PHP OSX.

With this package manager, the installation is only a few steps but he lists them out with a bit more detail to help you understand what's happening:

  • Installing PHP (your choice of version)
  • Configuring Apache (loading the php5 shared module)
  • Updating your PATH
  • Configuring PHP

How To Create Simple Rest API In Symfony 3.1
Aug 30, 2016 @ 12:59:10

The Cloudways blog has posted a new tutorial helping you get up and running quickly with a simple REST API written using the Symfony framework. In the article they not only explain how to create the API but also include a bit of REST theory for those not completely familiar with the terms and functionality involved.

Symfony is fast becoming the favourite framework among developers for rapid application development. And despite releasing Symfony 3.1 and 3.2 in the previous quarter, they are still introducing many changes and upgrades. If you’re still using the previous versions, you must upgrade Symfony Framework to the latest and stable version 3.1.

Yes! We know that Symfony is one of the best frameworks to develop rest API, so in this article we will make simple rest API in Symfony 3.1. I am assuming that you’ve already setup PHPstack application on Cloudways with Symfony installed, but if you haven’t, follow this installation guide.

They briefly talk about the REST HTTP verb types and what kind of actions they relate to. With that defined the tutorial then gets into the requirements including the installation of two bundles: JMSSerializerBundle and NelmioCorsBundle. From there examples of configuration changes, commands to make users and execute migrations on the local database are included. With this system set up they include sample code for each HTTP verb type letting you perform the actions on the User entity (create, read, update and delete).

Writing a Hello World PHP 7 Extension
Aug 25, 2016 @ 12:25:47

In a recent post to his site Alex Bowers shows you the steps involved in creating a "Hello World" PHP 7 extension with some basic output functionality - basically just echoing out a message.

He jumps right into the code and shows you how to:

  • set up the directory and initial files for the extension
  • write the test case first (a simple PHP file checking if it's loaded and can be used)
  • updating the config.m4 to allow for enabling the extension
  • the code for src/hello.h to define the function

The final piece is the code in the src/hello.c - the C code to define some structure for the PHP interpreter to understand and be able to execute the PHP_FUNCTION(hello_world). Finally he shows how to make the extension to install it, add it to your php.ini file as a shared module and re-run the test.

Laravel News:
Announcing Laravel Valet
May 06, 2016 @ 09:46:28

The Laravel News site Eric Barnes has a post about the latest addition to the Laravel ecosystem (that includes the framework, Envoyer and Homestead) - Laravel Valet.

Laravel Valet is the next generation development environment for Mac minimalists. No Vagrant, No Apache, No Nginx, No /etc/hosts file. “I wanted to have the convenience of php artisan serve without ever having to run php artisan serve“, Taylor said when asked why he created it.

Valet works by hooking into your Mac’s built-in PHP server then it utilizes DnsMasq to proxy all requests to the .dev TLD to sites on your local machine.

The post links to the official documentation and an article he's written up with a "first look" at the new tool.

Edd Mann:
Mapping, Filtering and Reducing in PHP
Mar 03, 2016 @ 09:28:27

Edd Mann has a post to his site talking about the use of things like "map" and "reduce" in his own development and how to use it in PHP to help reduce data sets and filter them based on certain criteria.

Over the past couple of years I have transitioned from boilerplate-heavy, imperative code, to begin using the more intuitive map, filter and reduce higher-order functions. In this article I hope to highlight the transformation that occurs, along with simplification, when moving away from the imperative and onto the declarative. We shall be performing a simple process which transforms a collection of user entries into a filtered collection of their names. Although trivial in nature, it is a great place to highlight the power of the paradigm shift.

He starts with a simple array of data: a set of users with their respective IDs and names. He shows a typical approach, using a method that loops through the data to find only the "name" values. He then shows an alternative that makes use of PHP's own array_filter and array_reduce functions to perform the same operation with just a bit more internal handling.
