Getting to Know and Love Xdebug
Apr 20, 2017 @ 17:55:59

On the SitePoint PHP blog editor Bruno Skvorc has posted a tutorial introducing you to Xdebug, the powerful debugging tool for PHP applications.

It’s been 15 years since Xdebug first came out. We think this is the perfect opportunity to re-introduce it to the world, and explain how and why it does what it does. Xdebug is a PHP extension (meaning it needs to be compiled and installed into a PHP installation) which provides the developer with some features for debugging.

It starts off by explaining some of the functionality that Xdebug brings to your debugging practices and the features that can help make it flow a little easier. It talks about how it differs from some of the IDE debugging tools and services like Blackfire.io. Next up is the example putting it to use and what the resulting errors look like. The post then gets into the integration of Vagrant with PhpStorm, using the profiler and how to force the rendering in Laravel output (it normally overrides the exception output with its own formatting).

Debugging a PHP application with strace
Mar 28, 2017 @ 11:24:43

On the Hackernoon.com site there's a recent post from Paolo Agostinetto showing you how to debug your PHP application with a different tool that most might use: strace.

Every once in a while it happens that you have a tricky bug, and when it does you risk to lose hours or even days fixing it.

[...] Yet, sometimes there is that one bug that makes you lose your shit after a whole afternoon spent looking for the root cause. In my experience, bugs that I introduce are generally very quick and easy to spot and fix. But the real challenge is finding bugs in other people’s code like third party libraries, PHP extensions or even PHP itself.

He then talks about a time when his situation was a bit different - he was getting 500 errors from his code that weren't being caught correctly by error handling. He found that Apache was out-of-memory-ing but debugging the exact cause (a suspect Doctrine query) would take more time. Instead he turned to strace and, with a bit of hunting in the resulting output, he tracked the issue down to XDebug being enabled (and a setting that was generating a memory leak).

Delicious Brains Blog:
Debugging JavaScript and PHP at the same time with PhpStorm
Feb 16, 2017 @ 11:14:20

The Delicious Brains site has a tutorial posted from author Peter Tasker showing you how to debug Javascript and PHP at the same time directly in your PHPStorm IDE.

Since I started with Delicious Brains last July, I’ve become a big fan of PhpStorm. It really is the bee’s knees. I won’t go over the full list of features, but some of the things I find helpful daily are: Cmd+clicking into method definitions, VCS integration and color highlighting of code changes, code bookmarks, and of course, Xdebug integration

In this post I want to expand on what Iain already covered with PhpStorm and Xdebug and show you how to level up your JavaScript debugging skills with PhpStorm.

The tutorial starts with a section explaining why using the PHPStorm debugger could be more beneficial and provide a more integrated workflow. It then starts in on the setup, showing how to set up the extension for Chrome so that it can talk to the IDE for the Javascript side complete with screenshots (and screencasts). With the two integrated the next step is to add a breakpoint in the code and what the results look like when it's executed and thrown.

The post finishes up covering the integration of the debugger with Xdebug allowing for the complete debugging of your application in one place.

Debugging collections
Jun 17, 2016 @ 09:47:42

Freek Van der Herten has a post to his site with a guide about debugging collections in Laravel applications. He quickly shows how to use the "macro" functionality to gather more insight into what's happening inside.

Lately I’ve been working a lot with collections in Laravel. If you’re not in the know: a collection is a sort of super charged array with a lot of powerful functions to transform the data inside it. The only thing I found a bit of a hassle is how to debug the various steps in a collection chain. Here’s how I improved the workflow.

He shows a simple collection setup with a chain of functions being applied to transform the data inside (ex: filter, map, sortBy). He was able to get a bit more information by using the dd helper Laravel provides but it's not the most "clean" way to just wrap the collection on it. Instead he proposes he use of a "macro" to call the dd function and keep it in the flow of the methods called on the collection (as ->dd()).

POST Request logger using websockets
Nov 17, 2015 @ 10:25:32

In this post to his site Gonzalo Ayuso shows you how to create a logger for your POST requests and their information with a bit of helpful code and Websockets.

Last days I’ve been working with background geolocation with an ionic application. There’s a cool plugin to do that. [...] Basically this plugin performs a POST request to the server with the GPS data. [...] I can develop a simple Silex application with a POST route and log the request in a file or flush those request to the console. This’d have been easy but as far as I’m a big fan of WebSockets (yes I must admit that I want to use WebSockets everywhere :) I had one idea in my mind.

He shows the creation of a simple Silex-based application with just two endpoints (channel that handles both GET and POST) that uses the Guzzle HTTP library to listen on the Websockets port for incoming connections. He then shows how to add the code necessary on the frontend (using express) to send the POST data automatically to the waiting Silex application. He's provided the full working code for the example on his GitHub account as well so you can see it fully fleshed out.

Easy debugging on CI with Mink
Sep 18, 2015 @ 09:44:12

On the Lakion blog there's a post showing you how to debug your application's Behat tests easily as a part of your continuous integration process. In thieir case, they were trying to figure out why builds were breaking on a Travis-CI build instance.

Debugging Behat scenarios while using Mink to simulate the user is not always an easy job. Especially, if they are run on Continuous Integration server. That is why I came up with an idea to make it easier. During repairing our javascript test suite on Sylius everything went as bad as it could go. There were many errors that happened on Travis, but I was not able to reproduce them locally. [...] MinkDebugExtension was written to speed up that boring and tiring part of debugging on CI server. It consists of two parts: Behat extension and useful scripts.

The extension fires after failed steps and makes a log of the issue with content needed to recreate the issue (including possible screenshots). He also describes the scripts that come with it to help you browse through the results, uploading the resulting logs and screenshots to a place for public consumption.

Drupal 8 Theming Revamped – Updates and New Features
Aug 11, 2015 @ 11:08:28

The SitePoint PHP blog has a tutorial posted introducing some of the updates to the theme functionality in Drupal 8 including some new features.

If you are a Drupal developer who has dabbled in theming older versions of Drupal (5, 6, 7) you understand why frustration is the trusty companion of any Drupal themer. Luckily, though, Drupal 8 promises so many improvements that even the Angry Themer is happy for a change. It is only natural we jump in and start looking at what these improvement are.

They talk about the changes in:

  • creating a module and defining its theme
  • that Twig is now the template library
  • updates to template handling
  • how to debug themes/templates
  • working with assets and libraries

Each topic includes a summary of the changes or more information about the topic including links to other resources with more information about each.

Debugging WordPress with Zend Server and Z-Ray on AWS
Aug 05, 2015 @ 11:57:02

The Zend.com blog has a post showing you how to debug WordPress running on Zend Server with the help of the Z-Ray plugin. In their example they're hosting it on an AWS instance, but the same technique can apply on any other hosted version as well.

More and more PHP development is being done in the cloud and on virtual platforms nowadays. The workflow detailed in this brief tutorial is just one way to develop PHP in these environments, but it illustrates just how easy and productive this type of development can be. More specifically, it demonstrates how to launch the newly available Zend Server 8.5 instance on AWS with a WordPress application already deployed, and then use Z-Ray to introspect and debug the code.

The tutorial walks you through the setup and configuration of a new AWS instance with Zend Server and WordPress installed (you can skip to the end if you already have this). They show you how to:

  • Launch the Zend Server AWS instance
  • Configure the instance to install WordPress as a part of the setup process
  • Access the Zend Server control panel
  • Accessing the WordPress application deployed on the instance

Once the WordPress application is accessed, the Z-Ray inspection bar will appear at the bottom giving you insight into various configuration options, performance metrics and server information. They also link to a video with more information about the WordPress plugin.

PHP Dumper using Websockets
May 11, 2015 @ 08:49:21

Gonzalo Ayuso has a quick post to his site showing you how to make a "PHP dumper" for websocket connections based on a simple Silex application.

Another crazy idea. I want to dump my backend output in the browser’s console. There’re several PHP dumpers. For example Raul Fraile’s LadyBug. There’re also libraries to do exactly what I want to do, such as Chrome Logger. But I wanted to use Websockets and dump values in real time, without waiting to the end of backend script. Why? The answer is simple: Because I wanted to it.

He shows how to create a simple socket server (with Express in Javascript) and the basic Silex application with a "DumperServiceProvider" added in that will handle returning the debugging data back to the waiting client. He connects the Silex application with the websocket and shows the code to listen for new messages on the socket and display them back out to the browser. You can see an example of the end result in this video on YouTube.
