Example #1 EventConfig::requireFeatures() example

`<?php
$cfg = new EventConfig();
// Create event_base associated with the config
$base = new EventBase($cfg);
// Require FDS feature
if ($cfg->requireFeatures(EventConfig::FEATURE_FDS)) {
echo "FDS feature is now requried\n";
$base = new EventBase($cfg);
($base->getFeatures() & EventConfig::FEATURE_FDS)
and print("FDS - arbitrary file descriptor types, and not just sockets\n");
