localtime

(PHP 4, PHP 5, PHP 7)

localtime — Get the local time

Description

localtime ([ int|null $timestamp = null [, bool $associative = false ]] ) : array

The localtime() function returns an array identical to that of the structure returned by the C function call.

Parameters

timestamp

The optional timestamp parameter is an int Unix timestamp that defaults to the current local time if timestamp is omitted or null. In other words, it defaults to the value of time().

associative

If set to false or not supplied then the array is returned as a regular, numerically indexed array. If the argument is set to true then localtime() returns an associative array containing all the different elements of the structure returned by the C function call to localtime. The names of the different keys of the associative array are as follows:

"tm_sec" - seconds, 0 to 59
"tm_min" - minutes, 0 to 59
"tm_hour" - hours, 0 to 23
"tm_mday" - day of the month, 1 to 31
"tm_mon" - month of the year, 0 (Jan) to 11 (Dec)
"tm_year" - years since 1900
"tm_wday" - day of the week, 0 (Sun) to 6 (Sat)
"tm_yday" - day of the year, 0 to 365
"tm_isdst" - is daylight savings time in effect? Positive if yes, 0 if not, negative if unknown.

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()

Changelog

Examples

Example #1 localtime() example

<?php
$localtime = localtime();
$localtime_assoc = localtime(time(), true);
print_r($localtime);
print_r($localtime_assoc);
?>

The above example will output something similar to:

Array
(
    [0] => 24
    [1] => 3
    [2] => 19
    [3] => 3
    [4] => 3
    [5] => 105
    [6] => 0
    [7] => 92
    [8] => 1
)

Array
(
    [tm_sec] => 24
    [tm_min] => 3
    [tm_hour] => 19

    [tm_mon] => 3
    [tm_year] => 105
    [tm_wday] => 0
    [tm_yday] => 92
    [tm_isdst] => 1
