idate
(PHP 5, PHP 7)
idate — Format a local time/date as integer
Description
idate
( string $format
[, int $timestamp
= time()
] ) : int
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.

The optional
timestamp
parameter is an int Unix timestamp that defaults to the current local time if atimestamp
is not given. In other words, it defaults to the value of time().
Return Values
Returns an int.
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.
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);?>
