# localtime

(PHP 4, PHP 5)

localtime -- Get the local time

## Description

array localtime ( [int timestamp [, bool is_associative]] )

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 than the array is returned as a regular, numerically indexed array. If the argument is set to `TRUE` then localtime() is 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

  - "tm_min" - minutes

  - "tm_hour" - hour

  - "tm_mday" - day of the month

    Months are from 0 (Jan) to 11 (Dec) and days of the week are from 0 (Sun) to 6 (Sat).

  - "tm_mon" - month of the year, starting with 0 for January

  - "tm_year" - Years since 1900

  - "tm_wday" - Day of the week

  - "tm_yday" - Day of the year

  - "tm_isdst" - Is daylight savings time in effect

## 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

Version | Description
--- | ---
5.1.0 | Now issues the `E_STRICT` and `E_NOTICE` time zone errors.

範例 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
    )
