Przykłady

Przykład 1. time_nanosleep() example <?php // Careful! This won't work as expected if an array is returned if (time_nanosleep(0, 500000000)) {     echo "Slept for half a second.\n"; } // This is better: if (time_nanosleep(0, 500000000) === true) {     echo "Slept for half a second.\n"; } // And this is the best: $nano = time_nanosleep(2, 100000); if ($nano === true) {     echo "Slept for 2 seconds, 100 milliseconds.\n"; } elseif ($nano === false) {     echo "Sleeping failed.\n"; } elseif (is_array($nano)) {     $seconds = $nano['seconds'];     $nanoseconds = $nano['nanoseconds'];     echo "Interrupted by a signal.\n";     echo "Time remaining: $seconds seconds, $nanoseconds nanoseconds."; } ?>
