Add signal handling support
- resource uv_signal_init([resource $loop]) - void uv_signal_start(resource $sigHandle, callable $onSignal, int $signal) - void uv_signal_stop($signalResource) Example: <?php $sigHandle = uv_signal_init(); $onSigint = function($sigHandle, $sigNum) { printf("Caught signal: %d\n", $sigNum); uv_signal_stop($sigHandle); uv_stop(); }; uv_signal_start($sigHandle, $onSigint, UV::SIGINT); uv_run(); New signal constants (these vary by OS): <?php $refl = new ReflectionClass('UV'); print_r($refl->getConstants());
