DateTimeZone::getTransitions -- timezone_transitions_get — 返回时区的所有转换
面向对象风格
$timestampBegin = PHP_INT_MIN, int $timestampEnd = PHP_INT_MAX): array|false过程式风格
$object, int $timestampBegin = PHP_INT_MIN, int $timestampEnd = PHP_INT_MAX): array|false如果成功，则返回一个以数字为索引的转换数组，否则返回 false。包裹类型 1（UTC 偏移量）和类型 2（缩写）的 DateTimeZone 对象不包含任何转换，并且在它们上调用此方法将返回 false。
如果提供了 timestampBegin，则返回的数组中的第一个条目将包含 timestampBegin 时刻的转换元素。

示例 #1 一个 timezone_transitions_get() 示例
<?php
$timezone = new DateTimeZone("Europe/London");
$transitions = $timezone->getTransitions();
print_r(array_slice($transitions, 0, 3));
?>上面的示例将输出类似以下内容
