PHP

Debugging Effectively

Web Developers Central NJ Meetup

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 upgraded my system from Ubuntu 16.04 with Unity to Ubuntu 17.10 with Gnome Shell 3. One of the "features" I found annoying was that my IDE PhpStorm was not popping to the front and receiving focus whenever breakpoints were hit. I eventually figured out a solution and wanted to document it in case others were also searching for a solution.

I first confirmed that "Focus application on breakpoint" was indeed enabled in my settings:

 

Magento has just released the SUPEE-10415 security patch for the following versions:

  • Magento Commerce 1.9.0.0-1.14.3.7 (formerly known as Enterprise Edition)
  • Magento Open Source 1.5.0.0-1.9.3.7 (formerly known as Community Edition)

The patch contains fixed for several security vulnerabilities including cross-site request forgery (CSRF), Denial-of-Service (DoS), and authenticated Admin user remote code execution (RCE).

 

I recently came across this really helpful PHP trick:

You can cast a numeric string to either int or float, depending on its contents, by simply adding 0:

var_dump("1" + 0);
// int(1)

var_dump("1." + 0);
// float(1)

var_dump("1.0" + 0);
// float(1)

var_dump("1.5" + 0);
// float(1.5)

That's much cleaner than trying to make a conditional cast yourself:

 

CommonMark - Markdown Done Right

ZendCon 2017

Markdown is one of the most popular markup languages on the web. Unfortunately, with no standard specification, every implementation works differently, producing varying results across different platforms. The CommonMark specification fixes this by providing an unambiguous syntax specification and a comprehensive suite of tests. In this session you'll learn about this standard and how to integrate the league/commonmark parser into their PHP applications. We'll also cover how to customize the library to implement new features like custom Markdown syntax or advanced renderers.
