PHP函数库分类十三
3. Date/Time函数列表(五)
? time - 返回当前的 Unix 时间戳
time — 返回当前的 Unix 时间戳
说明 int time ( void ) 返回自从 Unix 纪元(格林威治时间 1970 年 1 月 1 日 00:00:00)到当前时间的秒数。 Tip
自 PHP 5.1 起在 $_SERVER['REQUEST_TIME'] 中保存了发起该请求时刻的时间戳。
Example #1 time() 例子
$nextWeek = time() + (7 * 24 * 60 * 60);
// 7 days; 24 hours; 60 mins; 60secs echo 'Now: '. date('Y-m-d') .\;
echo 'Next Week: '. date('Y-m-d', $nextWeek) .\; ?>
以上例程的输出类似于:
Now: 2005-03-30 Next Week: 2005-04-07
? timezone_abbreviations_list - 别名 DateTimeZone::listAbbreviations
timezone_abbreviations_list — 别名 DateTimeZone::listAbbreviations()
说明 此函数是该函数的别名: DateTimeZone::listAbbreviations()
? timezone_identifiers_list - 别名 DateTimeZone::listIdentifiers
timezone_identifiers_list — 别名 DateTimeZone::listIdentifiers()
说明 此函数是该函数的别名: DateTimeZone::listIdentifiers()
? timezone_location_get - 别名 DateTimeZone::getLocation
timezone_location_get — 别名 DateTimeZone::getLocation()
说明 此函数是该函数的别名: DateTimeZone::getLocation()
? timezone_name_from_abbr - Returns the timezone name from abbreviation
timezone_name_from_abbr — Returns the timezone name from abbreviation
说明 string timezone_name_from_abbr ( string $abbr [, int $gmtOffset = -1 [, int$isdst = -1 ]] ) 参数 abbr
Time zone abbreviation.
gmtOffset
Offset from GMT in seconds. Defaults to -1 which means that first found time zone corresponding to abbr is returned. Otherwise exact offset is searched and only if
not found then the first time zone with any offset is returned.
isdst
Daylight saving time indicator. Defaults to -1, which means that whether the time zone has daylight saving or not is not taken into consideration when searching. If this is set to 1, then the gmtOffset is assumed to be an offset with daylight saving in effect; if 0,
then gmtOffset is assumed to be an offset without daylight saving in effect. If abbr doesn't exist then the time zone is searched solely by the gmtOffset and isdst.
返回值 Returns time zone name on success 或者在失败时返回 FALSE.
范例 Example #1 A timezone_name_from_abbr() example
echo timezone_name_from_abbr(\) . \;
echo timezone_name_from_abbr(\, 3600, 0) . \; ?>
以上例程的输出类似于:
Europe/Berlin Europe/Paris
? timezone_name_get - 别名 DateTimeZone::getName
timezone_name_get — 别名 DateTimeZone::getName()
说明 此函数是该函数的别名: DateTimeZone::getName()
? timezone_offset_get - 别名 DateTimeZone::getOffset
timezone_offset_get — 别名 DateTimeZone::getOffset()
说明 此函数是该函数的别名: DateTimeZone::getOffset()
? timezone_open - 别名 DateTimeZone::__construct
timezone_open — 别名 DateTimeZone::__construct()
说明 此函数是该函数的别名: DateTimeZone::__construct()
? timezone_transitions_get - 别名 DateTimeZone::getTransitions
timezone_transitions_get — 别名 DateTimeZone::getTransitions()
说明 此函数是该函数的别名: DateTimeZone::getTransitions()
? timezone_version_get - Gets the version of the timezonedb
timezone_version_get — Gets the version of the timezonedb

返回值 Returns a string. 范例 Example #1 Getting the timezonedb version
echo timezone_version_get(); ?>
以上例程的输出类似于:
