Re-Introducing Symfony Console – CLI PHP for the Uninitiated!
May 25, 2017 @ 11:38:02

The SitePoint PHP blog has posted a tutorial from author Claudio Ribeiro that wants to re-introduce you to the Symfony Console package, a component of the larger Symfony framework that makes it easier to create and work with command-line PHP scripts.

As software developers, we often feel the need to resort to command line tools. These kinds of tools are helpful when we need to do a sort of recurring task like migrating data, performing imports, or creating cron jobs.

The Symfony Console component tool provides us with a simple framework to create our own command line tools. Unlike many components in Symfony, this is a standalone package and is used by the likes of Laravel‘s Artisan and many other famous PHP packages.

The tutorial then walks you through the installation process, via Composer, and the creation of a new command. With this simple base created, he then adds in actual functionality, building out a command to hash and verify a password string. They show how to use the command and an example of its output. Next up, he creates another command example, this time verifying the password hash provided as an argument. The tutorial wraps up with a look at testing your console comamnds with PHPUnit tests via the included CommandTester functionality.

Re-Introducing Composer – the Cornerstone of Modern PHP Apps
May 22, 2017 @ 11:54:48

If you've been developing any kind of PHP applications lately, chances are you've at least heard of Composer. This package manager has dramatically changed the way we develop in PHP but there are still some out there wondering what all the fuss is about. In this tutorial from SitePoint author Claudio Ribeiro (re-)introduces this powerful tool and provides some basics of its use.

In this article, we will tackle the basics of Composer, and what makes it such a powerful and useful tool.

Before we go into detail, there are two things that we need to have in mind: what Composer is [and] what Composer is not. [...] Essentially, Composer allows you to declare and manage every dependency of your PHP projects.

He then walks you through the installation of the tool, running it either globally or locally (per-project). He lists out some of the basic commands, what they're for and helps you on your way to installing your first package: PHPUnit. He also covers the special "vendor" folder Composer creates, how autoloading works, various configuration values and installing packages globally rather than just locally. He then talks about the other side of the PHP package ecosystem: Packagist including how to submit packages and set up your own package's composer.json so it can be pulled in correctly.

Zend Framework Blog:
Leverage Zend Component Plugin Managers in Expressive
May 19, 2017 @ 09:58:15

The Zend Framework blog has a new post from project lead Matthew Weier O'Phinney showing how you can use plugin managers in Expressive and how it can be used to integrate other components.

With the release of Expressive 2, one of the key stories was the ability to require ZF components within Expressive, and have their dependencies auto-wired into your application courtesy of the component installer.

However, we recently had a user in our Slack channel (need an invite?) indicating they were having issues with usage of custom validators, filters, and input filters. After a <a href=https://discourse.zendframework.com/t/validatormanager-not-calling-custom-validator-factory/109">more thorough writeup on our forums, I realized we'd missed something important when making these integrations, and set out to solve it.

The article then starts with the problem that they're trying to solve, mostly around configuration handling. The solution involved some work done on various packages (like zend-log, zend-filter and zend-form) to make the configuration loading a bit more automated (and with fallback handling).

Scotch.io:
User Authorization in Laravel 5.4 with Spatie Laravel-Permission
May 16, 2017 @ 11:28:09

On the Scotch.io site a new tutorial has been posted showing you how to use the Laravel-permission package (from Spatie) to more easily handle permission setup and validation in a Laravel application.

When building an application, we often need to set up an access control list (ACL). An ACL specifies the level of permission granted to a user of an application. For example a user John may have the permission to read and write to a resource while another user Smith may have the permission only to read the resource.

In this tutorial, I will teach you how to add access control to a Laravel app using Laravel-permission package. For this tutorial we will build a simple blog application where users can be assigned different levels of permission.

The tutorial then walks though the installation of the package and some of the new tables it adds to the database when you run the included migrations. It then talks about some of the methods that can be used, both on the backend and in Blade templates, to evaluate if the current user has the roles required. Next up is the creation of the controllers to handle the basic CRUD tasks and working with the blog posts and views to set up the permissions and roles. Finally the tutorial shows the code required to evaluate the roles and permissions of the user and an example of middleware that performs a pre-check to see if a user even has access to manage various pieces of the application.

SitePoint PHP Blog:
PDS Skeleton by Example: A Standard for File and Folder Structure
May 15, 2017 @ 11:56:29

The SitePoint PHP blog has a tutorial posted by Younes Rafie introducing the php-pds/skelecton package definition and how it can be used to provide some structure and consistency across your package development.

Looking at the Packagist registry, we can see that most packages follow a pattern, with some small changes to fit their needs, while others have a weird folder structure that takes time to get your head around.

This problem has been solved in different ways by different people. Some frameworks have their own recommendations on how to structure your classes and assets, while others have a skeleton that you can use as a starting point. In this article, we’re going to explore the php-pds/skeleton and use it to build a small package as a demonstration.

He then uses a Laravel package example to show the build up of the package structure (based on the pds/skeleton definition). He goes through each portion of the skeleton structure talking about what they should contain:

  • config
  • resources
  • source files
  • tests
  • the "public" directory
  • bin/ folder
  • documentation
  • other files like README and LICENSE documents

He also suggests including a guide to contributing to the package and how to use the "validate" command to be sure this and the other items in the structure are in place.

BugSnag:
Packagist and the PHP ecosystem
May 11, 2017 @ 10:49:17

The BugSnag blog has posted a tutorial from a guest author, Graham Campbell, introducing you to Packagist and the PHP ecosystem continuing on from the previous post introducing the Composer tool.

In our last blog post we saw the basics of Composer, but skipped over where it actually finds its packages, and how to publish packages of your own. In this blog post, we will be looking at exactly this, plus some security considerations when using composer in your application.

The post starts off by introducing Packagist and how you can distribute your package there. There's a section that covers Open Source licenses, a few of the different types and how to list licenses of your currently installed packages. Following this the post talks about using branches and aliases to pull in the code you need (not just the latest release). The tutorial wraps up with a look at some of the security concerns around using packages and how to keep on top of new versions with new bugfixes.

QCode.in:
Easy roles and permissions in Laravel 5.4
May 03, 2017 @ 12:06:41

On the QCode.in site Saqueib Ansari has written up a tutorial showing how to use a package in Laravel applications to manage roles and permissions easily. This package, spatie/laravel-permission, compliments the current Laravel roles/permissions handling with a few handy features that make management and evaluation simpler.

Although laravel comes with Policies to handle the authorization but I wanted to have an option to just create permissions in the database which we can manage by a UI in the admin panel, pretty standard. we can implement our own role and permission from scratch but I am going to use [spatie/laravel-permission](https://github.com/spatie/laravel-permission) package for this. This package was inspired by Jeffrey ways screencast and it’s very well maintained and very easy to use. It has everything we need and plays very well with Laravel Gate and Policies implementations.

He walks through the creation of a new Laravel application, running the auth:make to generate the authentication functionality and adding the spatie/laravel-permission package to the service provider. He creates several models for permissions and roles and updates the User model with a new trait. Once the migrations are run, he creates a default permission set. Then it's on to the code for the endpoints to work with roles (including syncing them with permissions). He then moves over to the views, showing how to use the can helper to determine if a user has access, creating an Authorizable trait and an AuthorizationException handler. Finally the tutorial wraps up with the roles and permissions management functionality complete with code and screenshots of the result.

Zend Framework Blog:
Manage permissions with zend-permissions-rbac
May 02, 2017 @ 09:23:48

Continuing on from their previous tutorial looking at auth in Expressive middleware, the Zend Framework blog (and author Matthew Weier O'Phinney) shows an example of using the "zend-permissions-rbac" package from the Zend Framework to handle role-based access control in your application.

In our previous post, we covered authentication of a user via Expressive middleware. In that post, we indicated that we would later discuss authorization, which is the activity of checking if an authenticated user has permissions to perform a specific action, from within the context of a middleware application.

Before we do that, however, we thought we'd introduce zend-permissions-rbac, our lightweight role-based access control (RBAC) implementation.

The article starts off with the Composer command to get the package installed and some basic vocabulary around the role-based access control system. It then gets into some of the basics around creating a role and checking to see if a user (by identifier) has access to a permission. The post also includes an example of how to handle undefined roles more gracefully than the default exception. It goes on to cover role inheritance and the creation of a first "real world" example using the package for complex evaluation. This also includes assigning users roles using an Identity class and how to write custom assertions.

Freek van der Herten:
Dropbox will turn off v1 of their API soon. It’s time to update your PHP appli
Apr 24, 2017 @ 10:12:59

Freek van der Herten has a new post with both a reminder and a solution to an upcoming change from the Dropbox service: the disabling of their v1 API (and a PHP package you can use to be prepared).

Last year on 28th of June Dropbox deprecated v1 of their API. On the same date this year they will turn off all v1 endpoints. If you’re using using Flysystem, Laravel or the official PHP SDK to work with Dropbox, it’s the time to update.

Last week my company released a Dropbox API client and a Flysystem Dropbox adapter that both use v2 of the dropbox API. In this blogpost I’d like to explain how to install and use these packages.

He then shows you how to update your Flysystem adapters to use this new adapter for Dropbox - basically a simple code change once the package is installed. He then moves on to updating a Laravel application, configuring it's built-in file abstraction with the new adapter via a DropboxServiceProvider. The post ends with a bit talking about the update of other types of PHP applications (not using Flysystem) that could make use of other packages to make the required updates.
