php 한글 메뉴얼 도움말 검색 사이트 Sets the default timezone used by all date/time functions in a script [function.date-default-timezone-set]

설명

bool date_default_timezone_set ( string $timezone_identifier )

date_default_timezone_set() sets the default timezone used by all date/time functions.

Note:
Since PHP 5.1.0 (when the date/time functions were rewritten), every call to a date/time function will generate a E_NOTICE if the timezone isn't valid, and/or a E_WARNING message if using the system settings or the TZ environment variable.

Instead of using this function to set the default timezone in your script, you can also use the INI setting date.timezone to set the default timezone.

인수

timezone_identifier: The timezone identifier, like UTC or Europe/Lisbon. The list of valid identifiers is available in the 지원하는 시간대 목록.

반환값

This function returns FALSE if the timezone_identifier isn't valid, or TRUE otherwise.

예제

Example #1 Getting the default timezone


<?php
date_default_timezone_set('America/Los_Angeles');

$script_tz = date_default_timezone_get();

if (strcmp($script_tz, ini_get('date.timezone'))){
    echo 'Script timezone differs from ini-set timezone.';
} else {
    echo 'Script timezone and ini-set timezone match.';
}
?>

변경점

버전	설명
5.3.0	Now throws `E_WARNING` rather than `E_STRICT`.
5.1.2	The function started to validate the `timezone_identifier` parameter.
