<?php



arr|bool time_nanosleep ( int $seconds , int $nanoseconds )





where,

$nanoseconds = Number of nanoseconds to add to seconds



?>

$seconds

Number of seconds , (seconds), to delay the program execution.

Number of nseconds , (nanoseconds), to add to seconds to delay the program execution.

Since PHP 5.3.0 - this function is available on Windows.
