Coerced in two different ways

$x = NULL; if (‘0xFF’ == 255) { $x = (int)’0xFF’; } This problem tests your knowledge of how type juggling, or coercion works. When a string and a number are compared with the equality operator, the string is coerced

and, it’s not what you expected

$x = true and false; var_dump($x); This one is interesting. In PHP, you can use && or and to do a logical comparison. However, due to the Operator Precedence rules, and actually has lower precedence than =, where && has higher!

Testing your knowledge of array_merge

$arr = array(); $arr[‘val1’] = array(1, 2); $arr[‘val2’] = 3; $arr[‘val3’] = array(4, 5); $arr2 = array(); $arr2 = array_merge($arr2, $arr[‘val1’]); var_dump($arr2); $arr2 = array_merge($arr2, $arr[‘val2’]); var_dump($arr2); $arr2 = array_merge($arr2, $arr[‘val3′]); var_dump($arr2); There’s a problem with this code. It lies

Watch out for that Octal!

var_dump(0123 == 123); var_dump(‘0123’ == 123); var_dump(‘0123’ === 123); At first glance one might think that the leading zero on line one is simply of no value. But one would be wrong… In PHP, a leading zero in a number

strpos gotcha!

$string1 = ‘php is fun!’; $string2 = ‘php’; if (strpos($string1,$string2)) { echo “\”” . $string1 . “\” contains \”” . $string2 . “\””; } else { echo “\”” . $string1 . “\” does not contain \”” . $string2 . “\””;

Post-Fix Increment Problem with Solution

Today I saw an interesting problem. At first glance I wasn’t sure what I was looking at. It took me a moment to parse it. Here is my own version of the problem: $x = 3; echo $x; echo “<br

Making progress in Laravel

I’m making good progress in learning Laravel. I just wrote a service provider, and then created a Facade for it. The concepts are coming together nicely. Here are a few of the pages I used to help figure this out: https://laravel.com/docs/5.2/providers#registering-providers

Laracast: Laravel 5 Fundamentals

Today I’m starting the Laracast “Laravel 5 Fundamentals”. Let’s see how long it takes me to complete it…

Factories and base classes

Today I refactored some code, And for the first time ever I wrote a factory class. I have a class that calls a specific service on the web. I had that class directly referenced in other parts of my code.

PHP Architect’s Zend PHP Certification Study Guide

So, today I started chapter three, on arrays. I learned something new! The list() function. That may just come in handy someday. 🙂

The Checklist Manifesto

At SunshinePHP this year, at one of the talks, the speaker mentioned a book called “The Checklist Manifesto”. I started reading it yesterday and I’m halfway through it already. It’s a good read that explains why checklists are so vital

Sunshine PHP 2015

This year’s Sunshine PHP conference is only the second I’ve attended. My first was Tek in Chicago, in 2013. Having 2 years of PHP experience behind me now has made a big difference in my understanding of the topics presented

Which way is better?

While going though some code in a plugin (not one I wrote), I came across the following snippet: if ( !isset($update_transient->checked) ) return $update_transient; else $themes = $update_transient->checked; Looking at this makes me cringe. Here’s how I would write this:

2014: A look back

So here we are on the eve of a new year. 2014 has been a good one for me. I decided to look back over my posts for the year, and discovered that I only posted 10 times in 2014!
