Getting Time Difference

[mostafatalebi]

Hello everybody

 

I need a function in my site that calculates the period between two dates. How shall I approach this?

 

$date_1 - $date_2 = $period

 

I want to be able to get a time in clean appearance. Such as: 2 Days and 3 Hours

 

Thanks in advance

Sorry but is there a way to GMT Offset the time object in your function?

[Barand]

I'm not sure how you mean. From your question and the link I gave I am guessing that you now have something like this

 

   function myTimeDiff ($d1, $d2)
   {
    $dt1 = new DateTime($d1);
    return $dt1->diff(new DateTime($d2))->format('%a Days %h Hours');
   }

$date_1 = '2013-02-01 04:00:00';
$date_2 = '2013-02-03 07:30:00';

echo myTimeDiff($date_1, $date_2);    // --> 2 Days 3 Hours

 

What result are you getting and what result is required?

If you want to specify the timezone of the dates: You'll need to create a DateTimeZone object, of the desired timezone, then send it as the second parameter when creating the DateTime object.

 

If you want to retrieve the timezone, and its offset (compared to GMT), then you have the "e" and "O" flags for the DateTime::format () method.

 

You can also, if I'm not completely mistaken, change the timezone and automatically adjust the date/time of the object. To do this, just set the timezone using the proper method for the DateTime object.
