Introduction to TOML Configuration in PHP
Jul 30, 2018 @ 09:37:31

On the Laravel News site today there's a tutorial posted introducing you to TOML configuration, a new configuration file structure that's designed to be easy for humans to read and highly flexible (all while staying relatively simple).

TOML is a configuration file format language that is intended to be minimal and easy to read. TOML stands for “Tom’s Obvious, Minimal Language,” which refers to the creator Tom Preston-Werner.

[...] TOML aims to be a minimal configuration file format that’s easy to read due to obvious semantics. TOML is designed to map unambiguously to a hash table. TOML should be easy to parse into data structures in a wide variety of languages.

In order to work with it in PHP (since there is no native support) they show you how to install the yosymfony/toml package. The tutorial then walks you through an example TOML configuration file and what the result of using the package to parse it looks like. It then takes it a step further an converts one of the database configuration files for a Laravel application to the TOML format. It also shows the reverse - using the package to create a TOML file and the resulting output.

Matthias Noback:
About fixtures
Jul 10, 2018 @ 10:21:05

Matthias Noback has written up an article on his site covering a tool that's common in many web applications, especially for testing: fixture data. In the post he makes some suggestions about effective ways to use them to provide more "real world" results for tests.

System and integration tests need database fixtures. These fixtures should be representative and diverse enough to "fake" normal usage of the application, so that the tests using them will catch any issues that might occur once you deploy the application to the production environment. There are many different options for dealing with fixtures; let's explore some of them.

He makes four suggestions of ways to handle fixtures:

  1. Generate them the "natural" way via interaction with the application and taking a snapshot of the data.
  2. Generate them at runtime for the tests, reloading them each time
  3. Manual insertion of custom data into the database for all tests
  4. Manual insertion of custom data into the database for each test case

He finishes the post by asking a question for those considering using fixture data: do you need them at all? Testing should be isolated from external sources so maybe they're not really needed...

Implementing Custom Logic With Raw SQL In Laravel’s Query Builder
Jul 04, 2018 @ 12:19:35

The Pineco.de site has a new tutorial posted showing you how to implement custom logic with raw SQL in the Eloquent query builder in the Laravel framework.

Laravel’s query builder offers a nice way to work with raw SQL. We can use them in our where conditions and also in our orderings as well. Let’s see some examples where we can use raw SQL to implement custom logic for ordering the results.

The post starts with a brief mention of the difference between sorting and ordering results, noting that one happens on the SQL server and the other on the results collection. Next they show examples using raw SQL to order a query using both a simple and more complex condition. There's also a link to the official documentation for the raw methods for more information and examples.

Notifications in Laravel
Apr 24, 2018 @ 13:25:24

On the TutsPlus.com site they've posted a new tutorial for the Laravel users out there showing how to work with notifications, a feature build into the framework to make it simpler to provide information to users when certain events are triggered.

In this article, we're going to explore the notification system in the Laravel web framework. The notification system in Laravel allows you to send notifications to users over different channels. Today, we'll discuss how you can send notifications over the mail channel.

The tutorial starts with some of the basics of the notification system including a mention of the other methods (like SMS and Slack) and storing them in a database for other interaction. It then moves on to the creation of a Messages model and a custom notification class to send email to a when a new message is sent from another user. With the class created, they move into the process required to send the notification using the Notification::send method.

Laravel Exceptions: How to Catch, Handle and Create Your Own
Apr 23, 2018 @ 11:25:10

On the Laravel Daily site they've posted a tutorial showing the Laravel users out there how to create and catch custom exceptions in your application. Exceptions are a useful tool to handle "exceptional situations" where something fails badly enough where the application cannot proceed.

Quite often web-developers don’t care enough about errors. If something goes wrong, you often see default Laravel texts like “Whoops, something went wrong” or, even worse, the exception code, which is not helpful at all to the visitor. So I decided to write a step-by-step article of how to handle errors in elegant way and present proper error information to the visitor.

He uses a "user search" task to help illustrate the methods for creating custom exceptions, catch exceptions and showing the error to the user. Code is included as well as screenshots of the output. With the basics of exception handling out of the way, they move the handling off into a service and take it one step further to create a custom "user not found" exception and its use in the search method.

Creating custom stream filters in PHP
Apr 11, 2018 @ 09:45:43

Sameer Borate has a new post to his site showing you how to create custom stream filters for use with the streams functionality already included in the PHP language. The streams handling provides a resource instance (filesystem, network connection, etc) that can be interacted with in a more standardized way.

In this post we will see how to create a custom stream filter. Streams, first introduced in PHP 4.3, provide an abstraction layer for file access. A number of different resources besides files – like network connections, compression protocols etc. can be regarded as “streams” of data which can be serially read and written to.

He shows how to get the current list of streams available and includes an example of one in use, the "string.strip_tags" filter. From there he shows the creation of a custom filter, one that replaces any URLs detected in a string with a string of [--URL--]. He includes the code for the filter and shows how to register it using the stream_filter_register function. He also includes an example of it in use, grabbing the contents of the BBC site and having the filter automatically applied.

Try PSR-12 on Your Code Today
Apr 10, 2018 @ 10:51:19

In a post to his site Tomas Votruba shows you how to test the PSR-12 standard on your current codebase using some custom PHP-CS-Fixer rules. The PSR-12 standard is a recommendation from the PHP-FIG group about consistency in coding styles and formatting. It expands and replaces the previous PSR-2 standard.

The standard is still behind the door, but feedback, before it gets accepted, is very important. After accepting it will be written down and it will be difficult to change anything.

Try PSR-12 today and see, how it works for your code.

Korvin Szanto, a developer working on the PHP-CS-Fixer project, has put together a commit with the rules to update and enforce the PSR-12 coding standard. The post shows how to install these rules and how to change up your YAML configuration to include them. He also includes a discussion about agreeing/disagreeing with the coding standard idea and gives examples of two rules he personally doesn't agree with.

Laravel News:
User Defined Schedules in Laravel
Mar 09, 2018 @ 11:43:31

On the Laravel News site there's a new post looking at the use of user-defined schedules and some of the "hidden" features the Laravel framework provides to allow for even more customization.

Recently Adam Wathan and Taylor Otwell have used Basecamp to track what they are doing every day–a tech diary. Notably, they are using the check-in feature which allows you to schedule questions to be sent to members about almost anything. Taylor and Adam are using it for “What did you work on today?”

It’s not that it’s the same time of day or even that it’s only weekdays which peaked my curiosity but the fact every check-in has a custom schedule defined by a user. In Laravel, we can quickly schedule a job to run every weekday at 4 pm, and we can use a custom timezone. But out of the box, we cannot set a different schedule for every individual check-in. We would have to store a cron expression and manually check every minute if it’s due.

After some "source code diving" the author figured out that the Schedulable trait allows you to define a more customized version of a schedule to fit your needs, making it simple to implement in any class or model. Code examples of these changes are included in the post as well as some next steps to have it implemented more widely either in the Laravel core or a package.

Gates and Policies in Laravel
Nov 20, 2017 @ 12:46:28

On the TutsPlus.com site there's a new tutorial posted for the Laravel users out there covering a few pieces of the authorization features of the framework. The tutorial covers "gates" and "policies", introducing some of their basic concepts and providing example code to implement your own.

Today, we're going to discuss the authorization system of the Laravel web framework. The Laravel framework implements authorization in the form of gates and policies. After an introduction to gates and policies, I'll demonstrate the concepts by implementing a custom example.

I assume that you're already aware of the built-in Laravel authentication system as that's something essential in order to understand the concept of authorization. Obviously, the authorization system works in conjunction with the authentication system in order to identify the legitimate user session.

The article starts by introducing some of the basic approaches the framework takes to authorization handling and where gates and polices fit in. It then gets into the details of each including example code showing how to define them based on the interfaces provided. The tutorial then shows how to put them to use in a simple application, applying them at both the controller and view level.
