note 46152 added to function.sleep

I'm in trouble of sleep(). The least sleep time is as long as ONE second. But what I need is 10ms or 1ms. The sleep API of Windows is 1 millisecond quantitatively, and what in Unix is 1 microsecond. (Though it isn't so precision) Why do it 1 second in PHP? When you write a DB control with multithread php communication, the ONE second is too long for wait. ---- Manual Page -- http://www.php.net/manual/en/function.sleep.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46152 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46152&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+46152&report=yes Search -- http://master.php.net/manage/user-notes.php
