PHP: Add some milliseconds to a date() with strtotime()

Question

I need to add just 500ms to a specific date. To add, for example, 1 day to a date, I know I can write this:

$tomorrow = date("d-m-Y",strtotime("+1 day"));

To add 500 milliseconds to a date, instead, I tried with

strotime("+500 milliseconds",date(... 

but it's not working, date becomes 00-00 etc., or sometimes it remains the same.

Thanks for any help, Alberto

Answer 1

If you would like to work with milliseconds, you can check out microtime().

To advance the current time by 500 milliseconds ahead, you can use:

microtime(true) + 0.5
