tickertape
This library is no longer supported or maintained as PHP 5.2 usage levels have finally dropped below 10%
Fork of Symfony's Event Dispatcher component compatible with PHP 5.2+.
Motivation
Symfony's Event Dispatcher component is a fantastic library, but it's only compatible with PHP 5.3+. While 97% of PHP servers run PHP 5.2 or higher,
32% of all servers are still running PHP 5.2 or lower (source).
It would be a shame to exempt this library from nearly half of the world's servers just because of a few version incompatibilities.
Differences from Symfony's Event Dispatcher component
The primary difference is naming conventions of the Symfony classes.
Instead of the \Symfony\Component\EventDispatcher namespace (and sub-namespaces), prefix the Symfony class names
with ehough_tickertape and follow the PEAR naming convention
A few examples of class naming conversions:
\Symfony\Component\EventDispatcher\EventDispatcher -----> ehough_tickertape_EventDispatcher
\Symfony\Component\EventDispatcher\Event -----> ehough_tickertape_Event
Usage
$dispatcher = new ehough_tickertape_EventDispatcher(); //implements ehough_tickertape_EventDispatcherInterface
$dispatcher->addListener('event_name', $callback);
$dispatcher->dispatch('event_name');
Releases and Versioning
Releases are synchronized with the upstream Symfony repository. e.g. ehough/tickertape v2.3.1 has merged the code
from symfony/EventDispatcher v2.3.1.
