How to get a millisecond timestamp in PHP _php tips

The example in this article describes how PHP obtains a millisecond timestamp. Share to everyone for your reference. The specific analysis is as follows:

PHP itself does not provide a function to obtain a millisecond timestamp, which can be obtained by gettime (). If you want to perform a high precision millisecond docking communication with some of the programs that Java writes, you need to use PHP to output the millisecond-level time. The way I used to do that was to use the imprecise way, which is to add a three-digit number to the PHP native time function. To get a more accurate millisecond timestamp, you can use the following code:

<?php
function Getmillisecond () {
list ($t 1, $t 2) = Explode (", microtime ());
return (float) sprintf ('%.0f ', (Floatval ($t 1) +floatval ($t 2)) *1000);
Echo Getmillisecond ();

PS: Here again for you to recommend a local UNIX timestamp conversion tool, with a variety of languages (php/java/python/mysql, etc.) Unix timestamp operation methods:

I hope this article will help you with your PHP program design.
