[development] Note that PHP arrays are fast

Hi, Note my trick in http://drupal.org/node/134697 which shows that the hash lookups in Zend Engine are a bit faster than branching. Instead of $class = $class == 'even' ? 'odd' : 'even' we have $flip = array('even' => 'odd', 'odd' => 'even'); $class = $flip[$class]; The first can be as much as 10% slower. I will explore this area further and I recommend everyone to familiarize themselves with the vast array of php array functions :) because next Drupal will be even more abound with arrays. Regards, NK
