# time_nanosleep

(PHP 5)

time_nanosleep — Delay for a number of seconds and nanoseconds

### 설명

mixed time_nanosleep ( int `$seconds` , int `$nanoseconds` )

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

### 인수

`seconds`

  Must be a positive integer.

`nanoseconds`

  Must be a positive integer less than 1 billion.

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

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

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

### 변경점

버전 | 설명
--- | ---
5.3.0 | This function is now available on Windows platforms.

### 예제

Example #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 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.";
}
?>`

### 참고

- sleep() - Delay execution
- usleep() - Delay execution in microseconds
- time_sleep_until() - Make the script sleep until the specified time
- set_time_limit() - 최대 실행 시간을 제한
