idate

(PHP 5)

idate -- Format a local time/date as integer

Description

int idate ( string format [, int timestamp] )

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.

Parameters

format

Table 1. The following characters are recognized in the format parameter string

format characterDescription
BSwatch Beat/Internet Time
dDay of the month
hHour (12 hour format)
HHour (24 hour format)
iMinutes
Ireturns 1 if DST is activated, 0 otherwise
Lreturns 1 for leap year, 0 otherwise
mMonth number
sSeconds
tDays in current month
USeconds since the Unix Epoch - January 1 1970 00:00:00 GMT - this is the same as time()
wDay of the week (0 on Sunday)
WISO-8601 week number of year, weeks starting on Monday
yYear (1 or 2 digits - check note below)
YYear (4 digits)
zDay of the year
ZTimezone offset in seconds

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().

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 message if using the system settings or the TZ environment variable. See also date_default_timezone_set()

ChangeLog

VersionDescription
5.1.0

Now issues the E_STRICT and E_NOTICE time zone errors.

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);
?>
