IDATE(3) 1 IDATE(3)
idate - Format a local time/date as integer
SYNOPSIS
int idate (string $format, [int $timestamp = time()])
DESCRIPTION
Returns a number formatted according to the given format string using the given integer $timestamp or the current local time if no time-
stamp is given. In other words, $timestamp is optional and defaults to the value of time(3).

o $timestamp
- The optional $timestamp parameter is an integer Unix timestamp that defaults to the current local time if a $timestamp is not
given. In other words, it defaults to the value of time(3).
RETURN VALUES
Returns an integer.
As idate(3) always returns an integer and as they can't start with a "0", idate(3) may return fewer digits than you would expect. See the
example below.
ERRORS
/EXCEPTIONS
Every call to a date/time function will generate a E_NOTICE if the time zone is not valid, and/or a E_STRICT or E_WARNING message if using
the system settings or the $TZ environment variable. See also date_default_timezone_set(3)

EXAMPLES
Example #1
idate(3) example
<?php
$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);
?>
