Convert date to milliseconds in laravel using Carbon

Question

i make a date in laravel with carbon

$date = Carbon::createFromDate(2018,02,16);

how should i change it to milliseconds?

something like this:

18:16:30 -> 1532785457060

Answer 1

For get the timestamp in milliseconds you can use

$date = Carbon::now();
$timeInMilliseconds = $date->valueOf()

As a alternate solution

 $timeInMilliseconds = $date->getPreciseTimestamp(3)

Answer 2

You can convert any date. An example is below.

$dateWithMs = '2021-07-30 12:02:07.376000';

$timestamp = (int) round(Carbon::parse($date)->format('Uu') / pow(10, 6 - 3));

You should use Laravel >= 5.5 with Carbon 1.

It is working for me.

Answer 3

This works in laravel 5.5 with carbon 1.

$timestamp = (int) round(now()->format('Uu') / pow(10, 6 - 3));

this is actually what getPreciseTimestamp(3) in carbon2 does.
