IntlCalendar::fromDateTime — Create an IntlCalendar from a DateTime object or string
Object oriented style
Procedural style
Creates an IntlCalendar object either from a DateTime object or from a string from which a DateTime object can be built.
The new calendar will represent not only the same instant as the given DateTime (subject to precision loss for dates very far into the past or future), but also the same timezone (subject to the caveat that different timezone databases will be used, and therefore the results may differ).
dateTimeA DateTime object or a string that can be passed to DateTime::__construct().
The created IntlCalendar object or NULL in case of
failure. If a string is passed, any exception that occurs
inside the DateTime constructor is propagated.
Example #1 IntlCalendar::fromDateTime()
<?php
ini_set('date.timezone', 'Europe/Lisbon');
//same as IntlCalendar::fromDateTime(new DateTime(...))
$cal1 = IntlCalendar::fromDateTime('2013-02-28 00:01:02 Europe/Berlin');
//Note the timezone is Europe/Berlin, not the default Europe/Lisbon
echo IntlDateFormatter::formatObject($cal1, 'yyyy MMMM d HH:mm:ss VVVV', 'de_DE'), "\n";
The above example will output:
2013 Februar 28 00:01:02 Deutschland Zeit
