Examples

Example #1 IntlCalendar::fieldDifference()

<?php
ini_set
('date.timezone''Europe/Lisbon');
ini_set('intl.default_locale''fr_FR');

$cal1 IntlCalendar::fromDateTime('2012-02-29 09:00:11');
$cal2 IntlCalendar::fromDateTime('2013-03-01 09:19:29');
$time $cal2->getTime();

echo 
"Time before: "IntlDateFormatter::formatObject($cal1), "\n";

printf(
    
"The difference in time is %d year(s), %d month(s), "
  
"%d day(s), %d hour(s) and %d minute(s)\n",
    
$cal1->fieldDifference($timeIntlCalendar::FIELD_YEAR),
    
$cal1->fieldDifference($timeIntlCalendar::FIELD_MONTH),
    
$cal1->fieldDifference($timeIntlCalendar::FIELD_DAY_OF_MONTH),
    
$cal1->fieldDifference($timeIntlCalendar::FIELD_HOUR_OF_DAY),
    
$cal1->fieldDifference($timeIntlCalendar::FIELD_MINUTE)
);

//now it was advanced to the target time, exception for the seconds,
//for which we did not measure the difference
echo "Time after: "IntlDateFormatter::formatObject($cal1), "\n";

The above example will output:

Time before: 29 févr. 2012 09:00:11
The difference in time is 1 year(s), 0 month(s), 1 day(s), 0 hour(s) and 19 minute(s)
