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 required\n";

    $base = new EventBase($cfg);
    ($base->getFeatures() & EventConfig::FEATURE_FDS)
        and print "FDS - arbitrary file descriptor types, and not just sockets\n";
}
?>

Il precedente esempio visualizzerà qualcosa simile a:

FDS feature is now required
FDS - arbitrary file descriptor types, and not just sockets
