Getting microseconds, milliseconds and nanoseconds then converting them back to current time with PHP

07/04/2018 - PHP

I decided to add this very very simple post to demonstrate how we can get the current time in microseconds, milliseconds and nanoseconds then converting them back to current time again.


Example


// MILLISECONDS
$currentMilliSecond = (int) (microtime(true) * 1000);
echo 'CUR MILLISECONDS:'.$currentMilliSecond.PHP_EOL;
echo 'DATE:'.date('d/m/Y H:i:s', intval($currentMilliSecond/1000)).PHP_EOL;

// MICROSECONDS
$currentMicroSecond = (int) (microtime(true) * 1000000);
echo 'CUR MICROSECONDS:'.$currentMicroSecond.PHP_EOL;
echo 'DATE:'.date('d/m/Y H:i:s', intval($currentMicroSecond/1000000)).PHP_EOL;

// NANOSECONDS
$currentNanoSecond = (int) (microtime(true) * 1000000000);
echo 'CUR NANOSECONDS:'.$currentNanoSecond.PHP_EOL;
echo 'DATE:'.date('d/m/Y H:i:s', intval($currentNanoSecond/1000000000)).PHP_EOL;

Result


CUR MILLISECONDS:1523390684112
DATE:10/04/2018 16:04:44

CUR MICROSECONDS:1523390684112993
DATE:10/04/2018 16:04:44

CUR NANOSECONDS:1523390684113001984
DATE:10/04/2018 16:04:44
