Hướng dẫn sleep milliseconds in php

Does PHP provide a function to sleep in milliseconds?
Right now, I'm doing something similar to this, as a workaround.

$ms = 10000;
$seconds = round[$ms / 1000, 2];
sleep[$seconds];

I'd like to know whether there is a more generic function that is available in PHP to do this, or a better way of handling this.

This is your only pratical alternative: usleep - Delay execution in microseconds

So to sleep for two miliseconds:

usleep[ 2 * 1000 ];

To sleep for a quater of a second:

usleep[ 250000 ];

Note that sleep[] works with integers, sleep[0.25] would execute as sleep[0] Meaning this function would finish immediatly.

$i = 0;
while[ $i < 5000 ]
{
  sleep[0.25];
  echo '.';
  $i++;
}
echo 'done';
