I was noticing a lot of white (untouched) code in my XDebug code coverage reports however the method signatures at the top were all green and 100% covered. After some searching I found this thread (don’t bother reading) which led to this thread (scroll fast and occasionally read) which showed…

I finally get late static binding in PHP
Static inheritance in PHP (and really any language) can get tricky sometimes, especially when you’re trying to figure out what self is currently referring to. In PHP, self is always applied to the class that has that declaration, not necessarily the child class. Hmm… that reads weird, let’s make an…

PHP: Unexpected behavior when using unset() on class properties
When you unset a non-dynamic class property you apparently enter a weird limbo state. Take the following simple anonymous class: //Simple anonymous class, nothing to special $c = new class { public $alpha = ‘alpha’; }; Perform a property exists test and show the value: //Do we have the property? echo…

Optimize composer’s autoloader
Most people write really simple autoloaders for their PHP projects that look at a class or namespace prefix, perform a file_exists and finally require_once the file. Something like: //Register an autoloader for our plugin’s actual code spl_autoload_register( function ( $class ) { //PSR-4 compliant autoloader //See http://www.php-fig.org/psr/psr-4/ $prefixes = array(…

Firefox “Containers”
As of Firefox version 50 (version 52 is the current one) you can now open tabs in different “contexts” such as “work”, “personal” or “banking”. These “containers” as Firefox calls them are each isolated from each other which means that things like cookies aren’t shared between them. This means that…

strcspn
Going on 10 years of PHP programming and I’m still finding functions that I never knew about. Today it was strcspn which is one of those functions that essentially maps directly to a C counterpart. int strcspn ( string $subject , string $mask [, int $start [, int $length ]] ) The formal description…
