local time if a timestamp is not given. In other
words, it defaults to the value of time.
Return Values
Returns an integer.
As idate always returns an integer and
as they can't start with a "0", idate 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
Examples
Example #1 idate 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);
?>
