PHP 7.2 is slated for release in November 2017, but you don't have to wait until then to start testing your applications! We can easily use Docker to test against the latest pre-release versions of 7.2.
PHP 7.2 Pre-Release Images
I've created a PHP 7.2 pre-release image on Docker Hub: https://hub.docker.com/r/colinodell/php-7.2/.
All Things Open 2017
Software bugs are inevitable; some are especially difficult to track down, causing you to waste countless hours before throwing your hands up in defeat. It doesn't have to be this way! The mental fatigue and wasted time can be avoided by using strategies like identifying the most-appropriate tool, taking a logical & objective approach, challenging assumptions, listening to variables, isolating the code path, and reinforcing code with automated tests.
I recently needed the ability to perform a
RIGHT JOIN in a Symfony project. While Doctrine's DBAL library seems to support this, the ORM's QueryBuilder does not. Unfortunately, the suggested workaround of inverting the query wouldn't work in my situation. I also didn't feel like rewriting the query into DQL, so I ultimately hacked in my own support by duplicating the
LEFT JOIN functionality. I figured I'd share my patch in case it helps others facing a similar issue.
DrupalCon: Baltimore 2017
This talk educates junior and mid-level developers on common security vulnerabilities, how they are exploited, and how to protect against them. We'll explore several of the OWASP Top 10 attack vectors like SQL injection, XSS, CSRF, and others. Each topic will be approached from the perspective of an attacker to see how these vulnerabilities are detected and exploited using several realistic examples. We'll then apply this knowledge to see how web applications can be secured against such vulnerabilities.

The Internet of Things (IoT) is fundamentally changing how we interact with the digital world. In this talk, we’ll explore the implementation of live examples which bridge the gap between the physical and digital world using PHP: asking Alexa for information on php[world] conference sessions; displaying API data on an Arduino-powered display; using PHP to control LEDs on a Raspberry Pi to monitor application uptime; and connecting IR sensors to Slack to see whether a conference room is in use.
For Pi Day 2017 I created a really fun project - the PHPUnicorn!
A simple PHPUnit listener collects test results and sends them to a Raspberry Pi Zero Wireless device in real-time. As the device receives the stats it lights up LEDs green, red, or orange to visualize the progress and results of your unit tests.
TIL that Doctrine 2 doesn't support
LIMITs within subqueries which can be frustrating. In my case, I wanted to
LEFT JOIN on a table using a subquery with a single result - something like this:
$dqb->from('MyAppBundle:Foo', 'foo') ->leftJoin('foo.bar', 'bar', 'WITH', 'bar = (SELECT b FROM MyAppBundle:Bar b WHERE b.foo = foo AND b.published_date >= :now ORDER BY t.startDate LIMIT 1)');
But Doctrine kept throwing this error:
