在PHP中经过24小时的时间达到微秒

Question

I have to convert time in format of hh:mm:ss which is over 24hr, for instance 34:23:00. Is there any simple solution for this without using explode + strtotime functions?

Answer 1

This should do the trick

<?php
$inputTime = "34:23:00";
$timeSplitted = explode(":", $inputTime);
$microSeconds = ($timeSplitted[0]*3600 + $timeSplitted[1]*60 + $timeSplitted[2]*1)*1000;
var_dump($microSeconds); // int(123780000)

Answer 2

This should give you what you're looking for (assuming 1 second = 1000000 microseconds).

$time = '34:23:00';
$parts = explode(':', $time);   
$hours = !empty($parts[0]) ? $parts[0] : 0;
$minutes = !empty($parts[1]) ? $parts[1] : 0;
$seconds = !empty($parts[2]) ? $parts[2] : 0;

$microseconds = (($hours * 60 * 60) + ($minutes * 60) + ($seconds)) * 1000000;
