In versions of PHP before 5, constructors were functions with the same name as their class. PHP 5 introduced the __construct() unified name, and has deprecated the old style in PHP 7. Cogneato still has code remnants from long ago, with the old style. I recently worked on improving the compatibility of our old code with PHP 7.
Up way later than I wanted to be, fighting with Symfony’s framework bundle trapping PHP errors from getting to my Apache logs, and Apache’s ErrorLogFormat not being able to display REQUEST_URI. Gonna have to come back to these later.
