Get date and time from microtime

[spaze]

I use the following function to get microtime:

 

function microtime_float() {

  list($usec, $sec) = explode(" ", microtime());

  return ((float)$usec + (float)$sec);

}

 

How can I get date and time in microseconds?

You can use the date function to get the date in whatever format you like.

function microDateTime()
{
  list($microSec, $timeStamp) = explode(" ", microtime());
  return date('F jS, Y, H:i:', $timeStamp) . (date('s', $timeStamp) + $microSec);
}

echo microDateTime();
//Output: November 3rd, 2009, 15:38:38.671753

 

Modify format as needed

Just a thought. We use microtime, to get time reading with microsecond precision, but by enclosing microtime in function, we actually delay it's execution (how much?). Wouldn't it be more logical, to call microtime externally and pass it's result to the function that would do formatting only?

Good point. I guess it depends on what the purpose is. If I was running some start and end times of a process to gather metrics on performance I would probably include the microtime call int he function itself. Since each start and stop would have to call the function, the time to start the function should be "equivalent" if not for the single instance it should be over the long term.
