localtime — Get the local time

Description

localtime(?int $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: Determines whether the function should return a regular, numerically indexed array, or an associative one.

Return Values

If associative is set to false or not supplied then the array is returned as a regular, numerically indexed array. If associative is set to true then localtime() returns an associative array containing the elements of the structure returned by the C function call to localtime. The 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_WARNING if the time zone is not valid. See also date_default_timezone_set()

Changelog

Version	Description
8.0.0	`timestamp` is nullable now.

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
)
