localtime

(PHP 4, PHP 5)

localtime — Get the local time

Description

array localtime ([ int $timestamp = time() [, bool $is_associative = false ]] )

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 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().

is_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

Version Description
5.1.0

Now issues the E_STRICT and E_NOTICE time zone errors.

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