mixed time_nanosleep (int $seconds, int $nanoseconds) DESCRIPTION
Delays program execution for the given number of $seconds and $nanoseconds. PARAMETERS
o $seconds - Must be a non-negative integer. o $nanoseconds - Must be a non-negative integer less than 1 billion. RETURN VALUES
Returns TRUE on success or FALSE on failure. If the delay was interrupted by a signal, an associative array will be returned with the components: o seconds - number of seconds remaining in the delay o nanoseconds - number of nanoseconds remaining in the delay CHANGELOG

Example #1 time_nanosleep(3) 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. "; } // This is better: if (time_nanosleep(0, 500000000) === true) { echo "Slept for half a second. "; } // And this is the best: $nano = time_nanosleep(2, 100000); if ($nano === true) { echo "Slept for 2 seconds, 100 microseconds. "; } elseif ($nano === false) { echo "Sleeping failed. "; } elseif (is_array($nano)) { $seconds = $nano['seconds']; $nanoseconds = $nano['nanoseconds']; echo "Interrupted by a signal. "; echo "Time remaining: $seconds seconds, $nanoseconds nanoseconds."; } ?> SEE ALSO
