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…

Yahoo search result – CCC in front of page titles
In Yahoo’s search result some of our page titles were being prefixed the “C C C” which, of course, was really weird. Charlie figured this one out. My money was on some corrupt HTML tag that was trying to set a color to hex #CCC but that wasn’t right. Let me show…
