Adam Wathan:
Customizing Keys When Mapping Collections
Jul 19, 2016 @ 10:52:29

Adam Wathan has a new post to his site talking about mapping with collections and customizing the keys when injecting new data into your Laravel collections.

People often ask me, “how do I specify keys when I’m mapping a collection?”

It actually ends up being a pretty interesting topic, so I decided to cover it in a short screencast, as well as in written format below.

He shows how to translate a simple set of data into a much more slimmed down version. He points out that the "map" function could be used but it doesn't allow for setting keys. Instead he talks briefly about how the problem could be solved in Javascript (returning an object instead of an array) and how to use the "reduce" method to filter and reset the data as it goes through the array. He finishes out the post talking about learning from other languages, the "toAssoc" macro on Laravel collections and mapping the data back to an array with a custom macro.

Implementing Smart Search with Laravel and Typeahead.js
Jul 14, 2016 @ 12:12:41

The Scotch.io blog has posted a tutorial combining Laravel and the Typeahead.js library to create a "smart search" in your application. Most of the tutorial centers around the Typeahead.js code though, so with a bit of tweaking it could sit on top of just about any framework out there.

In a big web application, like an online market or a social network, one of the most important parts of the app is the search functionality. Having a great search feature will help your users find the right content(users, products, articles) quickly and easily.

In this tutorial, we are going to learn, how to enhance your default search field in your site with real-time suggestions from the database. We will be using Laravel, jQuery and Typeahead (Bloodhound as the suggestion engine) to implement the smart search and Bootstrap for the styling. So, let's get started.

He starts off by introducing the Typeahead.js library and the Bloodhound suggestion engine. He shows the installation (either via Bower, standalone download or included from a CDN) and a simple template with a search form and other Javascript requirements included. The tutorial covers some of the options you can set, what kinds of datasets it can work with and templates to use for the results. Next up, he brings in a default Laravel project and a "search" endpoint that queries user data and returns a JSON dataset of the results. The two pieces are then finally tied together with a few updates to the Javascript already created.

Matt Stauffer:
Introducing Laravel Echo: An In-Depth Walk-Through
Jun 17, 2016 @ 12:11:02

Matt Stauffer has a new post to his site where he's put together an in-depth look at Laravel Echo, a feature included in newer versions of the framework that makes it easy to integrate websockets into your Laravel-based application.

A few weeks ago, Taylor Otwell introduced another branded product within the Laravel line: Laravel Echo. So far, the only coverage it's gotten has been his Laracasts video intro, but I recently wrote it up for my book and wanted to share that with you. What follows is an excerpt from Laravel: Up and Running, heavily modified to make sense in a blog format.

He then gets into what Echo is and the different pieces that make it up: updates to the Laravel broadcast system and a new Javascript package. He suggests some places where using Echo makes sense and how to set up a simple broadcast event in your application (non-Echo to start). This makes use of the Pusher service for real-time event broadcasting. With that in place, he helps you install the Echo dependencies and integrating messages from both public and private channels. He also includes a bit of code at the end to exclude the message from broadcasting to the current user if you ever find a need for it.

How Will REST API Affect WordPress Developers?
Feb 03, 2016 @ 10:48:31

On the Noupe.com site they've posted an article talking about the WordPress REST API that's been included by default in the project and how it will affect developers on the platform.

With the advent of WordPress 4.4 last year in December, we saw the inclusion of the first half of REST API in the WordPress Core, and the rest of it is expected to be with us in the upcoming major release of WordPress. [...] The community is abuzz with all talks about how important REST API will soon be for WordPress development, and how it is going to change the way developers code and interact with WP.

So, how is REST API going to affect the WordPress users and developers, and what exactly will we be able to accomplish using it?

In the article they talk about the impact that the API will have on the "rise of Javascript" in the WordPress application and the role PHP could play in it all. They also talk about cross-platform integrations the REST API makes possible, the Calypso interface that was recently announced and how it opens up a new world of mobile application possibilities.

WP REST API: Setting Up and Using Basic Authentication
Jan 08, 2016 @ 11:37:58

On the NetTuts.com site there's a tutorial posted showing you how to set up and use basic authentication in the WordPress REST API. This is part two in their series introducing the WordPress REST API.

In the introductory part of this series, we had a quick refresher on REST architecture and how it can help us create better applications. [...] In the current part of the series, we will set up a basic authentication protocol on the server to send authenticated requests to perform various tasks through the REST API.

They talk about the methods that are available for authentication and how to configure your server and WordPress instance to use it. From there they show how to make authenticated requests to the API using various tools:

  • Postman
  • a Javascript framework (jQuery)
  • the command line via curl
  • using the WP HTTP API

Example code and screenshots are provided for each (where appropriate) helping to ensure you're up and working quickly.

Automatic Asset Optimization with Munee
Oct 12, 2015 @ 10:26:42

The SitePoint PHP blog has posted a tutorial showing you how to optimize how your application works with assets with Munee.

Munee is a n asset management tool which can compile LESS, SCSS, or CoffeeScript, manipulate images, minify CSS and JS, and cache assets on the server and client on the fly. It works with PHP 5.3 and newer versions.

In this tutorial, we will learn how Munee makes it easy to include assets in templates, how to install it, how it works and how to use it. Munee is another way to avoid NodeJS in asset management of PHP apps.

He starts the article with a few reasons why you'd want to use Munee to manage your application's assets including automatic minification and both server and client side cache handling. He covers a bit about how it works and what it does to cache assets via simple HTTP headers. He then gets into the actual installation of the tool, the code needed to run it in your system (a one-line call) and how to have the server rewrite all the requests back to the waiting PHP file. He shows how to compile different asset types including SCSS, LESS and CoffeScript files as well as minifying Javascript and CSS. Munee also includes an on-the-fly image resize handler that will also cache the results. Finally he talks about how you can use it to combine assets and briefly about the API the library provides for some other functionality.

SitePoint PHP Blog:
An Introduction into Event Loops in PHP
Sep 10, 2015 @ 10:06:55

The SitePoint PHP blog has posted a tutorial from Christopher Pitt introducing you to using event loops in PHP, a feature that allows for asynchronous processing, executing code while waiting for other code to finish.

PHP developers are always waiting for something. Sometimes we’re waiting for requests to remote services. Sometimes we’re waiting for databases to return rows from a complex query. Wouldn’t it be great if we could do other things during all that waiting?

If you’ve written some JS, you’re probably familiar with callbacks and DOM events. And though we have callbacks in PHP, they don’t work in quite the same way. That’s thanks to a feature called the event loop.

He starts by explaining event loops with an example from a language that naturally supports it - Javascript. He includes another example using the setTimeout function in Javascript to show a simple loop but points out that PHP just doesn't support this same kind of handling (code included). So, how can you simulate the loop like in JS? He links to and includes a examples of two libraries that could be dropped in and used to do the hard work behind the scenes of the looping:

He suggests that PHP developer "get out of the single threaded mindset" and work in ways to handle asynchronous processing into their code to improve performance and flexibility.

Programming With Yii2: Working With Asset Bundles
Jun 10, 2015 @ 10:42:30

NetTuts.com is back with another part in their "Programming with Yii2" series today. In this new post they focus on asset bundles, pieces of functionality that let you easily manage things like Javascript and CSS files automatically.

In this Programming With Yii2 series, I'm guiding readers in use of the newly upgraded Yii2 Framework for PHP. In this tutorial, I'll show you how to add custom JavaScript and CSS scripts and libraries to your Yii application. Yii uses a concept it calls Asset Bundles to make it easier to manage these resources. For these examples, we'll continue to build on the simple status application from previous tutorials.

They start with an introduction to asset bundles and how to set them up in the framework and the resulting HTML markup to include the involved files. They show you how to create a simple bundle and load it into your application. A screenshot is included showing a result of the inclusion.

Anthony Ferrara:
Tries and Lexers
May 18, 2015 @ 09:47:32

Anthony Ferrara has an interesting new post to his site talking about tries and lexers, two pieces of a puzzle that are used during script execution. In this case, he's tried his hand at writing a parser which, naturally, lead to needing a lexer.

Lately I have been playing around with a few experimental projects. The current one started when I tried to make a templating engine. Not just an ordinary one, but one that understood the context of a variable so it could encode/escape it properly. [...] So, while working on the templating engine, I needed to build a parser. Well, actually, I needed to build 4 parsers. [...] I decided to hand write this dual-mode parser. It went a lot easier than I expected. In a few hours, I had the prototype built which could fully parse Twig-style syntax (or a subset of it) including a more-or-less standards-compliant HTML parser. [...] But I ran into a problem. I didn't have a lexer...

He starts with a brief description of what a lexer is and provides a simple example of an expression and how it would be parsed into its tokens. He then talks about the trie, a method for "walking" the input and representing the results in a tree structure. He shows a simple implementation of it in PHP, iterating over a set of tokens and the array results it produces. He then takes this and expands it out a bit into a "lex" function that iterates over the string and compiles the found tokens.

From there he comes back to the subject of Javascript, pointing out that it's a lot looser than PHP in how it even just allows numbers to be defined. His testing showed a major issue though - memory consumption. He found that a regular expression method consumed too much and tried compiling out to classes instead (and found it much faster once the process was going).
