I use echo date('H:i:s')." this step time\n";

How to find out the time in microseconds?

Answer 1

Just add the PHP microtime () function , which can be used as follows:

$time_start = microtime(true);

//do stuff here

$time_end = microtime(true);
$time = $time_end - $time_start;

echo "It took $time seconds\n";
