How to get current time in ms in PHP?

I am trying to figure out the best way to get the current time in milliseconds. As a company I am doing work for stores milliseconds in a database as they lay claim that its more accurate as far as UTC conversion goes. They obtain most of these times via javascripts date function. So what I am trying to figure is what is the best way to do this php side. I see mixed results.

time()*1000 seems to be popular, but for me that doesnt make sense, as your ending up with a normal timestamp with 3 additional zeros at the end, which yea thats closer to accurate, but still not exact. I have also seen

microtime(time(), TRUE) or something to the extent there of, but that returns a result with a decimal from what I gather. Which again isn’t up to par with what I am looking for. That said. Whats the best approach to getting a javascript readable version of a javascript style timestamp created by PHP on the fly?

Answer 1

microtime(time(), TRUE) is not valid and time()*1000 would not give you the best result

You can try

Javascript

 document.write(new Date().getTime()); // 1348773527231

PHP

print(round(microtime(true) * 1000)); // 1348773528231
