PHP Microtime Diff -- Calculate a precise time difference - microtime_diff.php. Star 8 Fork 3 CodeManFantastic March 2, 2018, 11:38am #9 I … For instance: Time In: 11:35:20 (hh:mm:ss), now say the current time is: 12:00:45 (hh:mm:ss) then the time difference in my formula gives the output: 1:-34:25.It should actually be: 25:25 REQUEST_TIME_FLOAT The timestamp of the start of the request, with microsecond precision.

(Available since PHP 5.1.0.) - This function checks the keys of the arrays, array_diff only compares the values. While doing some experiments on using microtime()'s output for an entropy generator I found that its microsecond value was always quantified to the nearest hundreds (i.e. Questions: I can’t wrap my brain around this one so I hope someone can help.
