Example #1 pcntl_signal_dispatch() example
<?php
echo "Installing signal handler...\n";
pcntl_signal(SIGHUP, function($signo) {
echo "signal handler called\n";
});
echo "Generating signal SIGHUP to self...\n";
posix_kill(posix_getpid(), SIGHUP);
echo "Dispatching...\n";
pcntl_signal_dispatch();
echo "Done\n";
