idate — Format a local time/date part as integer
Returns a number formatted according to the given format string using the
given integer timestamp or the current local time
if no timestamp is given. In other words, timestamp
is optional and defaults to the value of time().
Unlike the function date(), idate()
accepts just one char in the format parameter.

timestamp
Необов'язковий параметр timestamp — це позначка часу Unix
типу int, яка стандартно дорівнює поточному місцевому часу, якщо
timestamp не вказаний або null. Тобто є результатом
функції time().
Returns an int on success, або false в разі помилки.
As idate() always returns an int and as they can't start with a "0", idate() may return fewer digits than you would expect. See the example below.

$timestamp = strtotime('1st January 2004'); //1072915200
// this prints the year in a two digit format
// however, as this would start with a "0", it
// only prints "4"
echo idate('y', $timestamp);
?>
