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");
}
?>
