time_nanosleep

Delay for a number of seconds and nanoseconds

 **time_nanosleep** int $seconds int $nanoseconds

Delays program execution for the given number of and . seconds``nanoseconds

secondsMust be a non-negative integer.

nanosecondsMust be a non-negative integer less than 1 billion.

Opmerking: > On Windows, the system may sleep longer that the given number of nanoseconds, depending on the hardware.

return.success

If the delay was interrupted by a signal, an associative array will be returned with the components:

    • number of seconds remaining in the delay seconds
    • number of nanoseconds remaining in the delay nanoseconds

    Voorbeeld: 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 ($nano === true) {
    echo "Slept for 2 seconds, 100 microseconds.\n";
} elseif ($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.";
}
