How to calculate time in php
Hi All I'm trying to calculate elapsed time in php. The problem is not in php, it's with my mathematical skills. 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 Show
Any help please? EDIT Sorry I probably had to add that the page refreshes every second to display the new elapsed time so I have to use my method above. My apologies for not explaining correctly. asked Oct 21, 2011 at 13:42

To display it clock-style afterwards, you'd do something like this:
If you don't want to display the numbers after the decimal, just add answered Oct 21, 2011 at 13:44

And then you can compare that to another value later on. Use microtime if you need millisecond detail. answered Oct 21, 2011 at 13:47

The advantage is that you can usually define the timer to be active or not, thereby permitting you to leave the timer calls in your code for later reference without re-keying all the time points. answered Oct 21, 2011 at 14:18

Using strtotime() function: The strtotime() function is used to convert string into the time format. This functions returns the time
in h:m:s format. strtotime( string ) Example 1: This example reads the values from the array and converts it into the time format. php
Using explode() function: The explode() function is used to break a string into an array. array explode( separator, string, limit ) Example 2: This example reads the values from an array and converts it into the time
format. php

How does php calculate start and end time?calculate total time from start and end datetime in php. date1 = new DateTime('2006-04-12T12:30:00');. $date2 = new DateTime('2006-04-14T11:30:00');. $diff = $date2->diff($date1);. $hours = $diff->h;. $hours = $hours + ($diff->days*24);. How can I calculate hours between two dates in php?You can convert them to timestamps and go from there: $hourdiff = round((strtotime($time1) - strtotime($time2))/3600, 1);
