Conquering Instagram with PHP and the Instagram API
Sep 22, 2015 @ 12:57:21

The SitePoint PHP blog has a tutorial posted that shows you how to "conquer" the Instagram API in your PHP application and integrate it into your application with the help of the Guzzle HTTP client.

Instagram’s API allows us to interact with data such as user info, media (photos and videos), likes, comments, and tags. For example, you can search for media around a specific location and filter the results by time. The API also allows us to post comments or like specific media. For now, only uploading media isn’t supported. You can always look at the API endpoints documentation if you want to know about the full functionality.

They start by talking about the two types of API calls (authenticated/unautheticated) and the limits that are included with each. From there the tutorial shows you how to register a new application, get a new client ID and how to use the API console to test out requests. Next they help you get the [Guzzle]((http://guzzle.readthedocs.org/en/latest/) library installed and connect it to the Instagram API with your client credentials. They integrate this into a simple Slim application using Twig as a templating layer to allow for the OAuth approval process, fetching an access token for the later requests.

With the connection made, they show you how to make requests to do thing like make tag searches, get user feed information (and searches), geographic searches and handling pagination. They also include a link to a PHP Instagram library that can help simplify the process, complete with code examples.

Removing the Pain of User Authorization with Sentinel
Sep 21, 2015 @ 14:23:10

The SitePoint PHP blog has posted a tutorial showing you how to "take the pain out of user authorization" with the help of Sentinel, a package from Cartalyst that already includes functionality for both user authorization and authentication.

Most non-basic multi-user applications need some roles and permission levels. If you ever used WordPress, you must have noticed that they have a super admin, admin, editor, author, etc. Simplifying the development and integration of a permission system is what Cartalyst’s Sentinel package is trying to accomplish. The package provides an API for dealing with users, groups, permissions, etc. In this article, we’ll use it to create a small demo app.

They walk through the creation of a simple Slim framework application, installing it, Sentinel and other suggested packages via Composer. They then help you execute the migrations to create the necessary tables and set up a basic front controller file. From there they configure Twig templating, the Illuminate database connection and finally adding a Sentinel instance to the application's DI container. They include code to help you create roles for "user" and "admin". From there the tutorial shows how to create a login & registration form, send a registration email, create permissions and activating users. Finally they build a simple administration page that allows you to hide functionality from normal users.

Matthew Setter:
Why Microframeworks Lead to Lean Applications
Sep 03, 2015 @ 10:17:35

Matthew Setter as a post on his site that suggests that microframeworks make for lean applications, such as one he recent built using the Slim framework.

Recently I built a new application using SlimPHP, a PHP microframework, instead of a full-stack framework, such as Symfony or Zend Framework 2. In this post, I start discussing how taking this approach has lead to a leaner application design. [...] Before I get too far along, I want to make one thing clear, I'm not bagging full-stack frameworks. [...] Technically, you don't need to bring in more than you need. However, often times, these frameworks still do have a lot of overhead which you may, typically, never need. [...] Whereas microframeworks, assuming they follow The MicroPHP Manifesto, especially SlimPHP, give you the minimum you need to start building a web application.

He goes on to talk about why he made the choice of Slim for his application and describes a bit about what the application does. He talks about some of his main needs when creating the site and how Slim matched up with most of them (with a little help from a few other packages). He included other libraries for YAML parsing, Markdown output formatting, caching and others to round out the application but Slim was at the heart of it. He ends the post by pointing out that taking this lightweight approach was a perfect fit for his project and that, while there were other choices, Slim fit his needs best.

First beta of Slim Framework 3
Jul 03, 2015 @ 08:03:18

Rob Allen has a new post about the tagging of the first beta of Slim Framework v3, the popular PHP microframework's latest version. In it he details a few of the major changes and requests help testing.

Last night, I tagged beta 1 of Slim Framework 3! This is a significant upgrade to v2 with a number of changes that you can read on the Slim blog. For me, the two key features that I'm most excited about are: PSR-7 support, [...and a] dependency injection container with container-interop compliance. [...] There's lots of other changes and we believe we have kept to the key tenants of Slim, keeping it focussed as a micro-framework suitable for building any application that you want to build.

He includes everything you'll need to test this newly tagged release with the help of his skeleton application. He also links to the new documentation that's a work in progress to replace the current set of docs. You can find more information on the full list of changes over on the Slim blog.

Accessing services in Slim 3
Jun 23, 2015 @ 10:51:36

Rob Allen has a new post to his site today showing you how to access services in a Slim 3 application using container injection instead of the previous "getInstance" method.

One of the changes between Slim Framework 2 and 3 is that the application singleton has gone. [...] In general, you didn't need access to $app itself, but rather you wanted access to something that the app knows about, such as a database adapter, or the router for access to the urlFor method to create a URL to a route. With Slim 3, there is no getInstance() on App, so you need to inject the instances of whatever you need where ever you need them.

He shows you how to create a simple Slim dependency injection container (service locator?) and push two kinds of objects in for later reuse. He shows how to reference this container from inside of your routes in both the callable/closure and class contexts. He also includes an example of referencing the same container from inside middleware (again in both the closure and class contexts).

Using ZendConfig with a Slim app
Apr 21, 2015 @ 09:11:31

Rob Allen has a quick post to his site continuing his theme of Slim framework-related posts with this new post showing how to use the ZendConfig module with a Slim application.

Sometimes you need more configuration flexibility for your application than a single array. In these situations, I use the ZendConfig component which I install via composer: composer require "zendframework/zend-config". This will install the ZendConfig component, along with its dependency ZendStdlib.

He shows how to use the glob function to have the component load a set of configuration files and the order they'd load in. He also points out that the ZendConfig component supports other formats including YAML and JSON data. He also includes a code example showing how you can load multiple formats at the same time (ex. some .php files and some .yml files with one call).

Slim Framework Blog:
Apr 17, 2015 @ 09:34:17

Josh Lockart, the lead developer and creator of the Slim framework, has responded to some questions and comments around the recently released Laravel microframework Lumen and how it relates to Slim and its own goals.

Lumen happened. It’s a shiny new micro-framework from Taylor Otwell, and it joins the Laravel family today. It looks to be a pretty nice framework, and it shares many of the same features and goals as Slim 3.0. I’m sure this raises a few question about Slim’s future roadmap. [...] Is there overlap between Slim and Lumen? Of course. They both have similar goals and solve similar problems. There are also differences.

He talks about some of the current work being done on version 3.0 of Slim, the PSR-7 support it offers and some of the differences between Slim and Lumen. He points out two main ones: that Slim has fewer dependencies and that it is a supporter of the PSR-7 HTTP interoperability standard. Josh talks about why you might choose Lumen over Slim and that, in the end, he welcomes alternative microframeworks and challenges the Slim community to help consistently improve Slim and its place in the community.

Logging errors in Slim 3
Apr 07, 2015 @ 10:57:36

Rob Allen continues his posts looking at the use of the Slim PHP framework with this new post about logging errors.

Slim Framework 3 is being actively developed at the moment and has a number of changes in it, including the use of the Pimple DI container and an overhaul of pretty much everything else! In this post, I'm going to look at error handling. The default error handler in Slim 3 is SlimHandlersError. It's fairly simple and renders the error quite nicely, setting the HTTP status to 500. I want to log these errors via monolog.

He includes the code to first set up the Monolog logger and inject it into the dependency injection container. Then he creates a custom error handler that extends the Slim handler but overrides the __invoke method to log the message in addition to displaying it. Finally he registers the error handler into the DI container as the "errorHandler" instance so Pimple correctly knows how to throw errors.

Sameer Borate:
Create a quick REST API using Slim framework
Mar 16, 2015 @ 10:16:40

Sameer Borate has a quick tutorial posted showing how to create a basic REST API with Slim, the popular microframework for PHP.

During a recent client project, I frequently needed to access a remote database table and update the same for certain fields. This was accomplished using phpMyAdmin on the server. However, it was getting tedious and was prone to accidental updates and deletes. [...] This is all a tedious process and prone to errors. One solution was to create a quick REST api wrapper around the remote database, using which developers could update the database table without any risk of corrupting the data and also with the added benefit of updating the table programmatically.

He uses an example of working with student data (SQL for the table included) and helps you get Slim installed and working with an Apache install. He covers the overall structure of the API he's creating and the code to help make it happen. Obviously he doesn't share the entire codebase - that would be too large. He does show examples of GET and POST requests for the student data to give you something to work from. He finishes the post with a few simple cURL calls to make requests to the API and the responses.

Rob Allen:
Routing to a controller with Slim
Feb 18, 2015 @ 10:19:08

Rob Allen has a new post today sharing an extension for Slim he's written to make working with controllers easier.

In a couple of projects that I've written using Slim Framework, I've found it beneficial to organise my code into controllers with injected dependencies; probably because that's how I'm used to working with ZF2. To make this easier, I've written an extension to the main Slim class and packaged it into rka-slim-controller which will dynamically instantiate controllers for you for each route.

His library makes it easy to define controller "paths" instead of the typical closures Slim requires to direct the request to a controller file. He gives several example routes, the code that the controller needs and shows how you can inject objects into the constructor of the controller (dependency injection).
