How can PHP functions like getTransitions() be utilized for managing daylight saving time transitions?

To manage daylight saving time transitions using PHP functions like getTransitions(), you can retrieve an array of transitions for a specific timezone and year. This array will contain information about the start and end timestamps for each transition, allowing you to adjust your application's behavior accordingly when transitioning between standard time and daylight saving time. 

// Get transitions for a specific timezone and year
$transitions = timezone_transitions_get(
    timezone_open('America/New_York'),
    strtotime('2022-01-01'),
    strtotime('2022-12-31')
);

// Iterate through transitions and handle accordingly
foreach ($transitions as $transition) {
    echo 'Transition from ' . date('Y-m-d H:i:s', $transition['ts']) . ' to ' . $transition['time'] . ' with offset ' . $transition['offset'] . ' seconds.' . PHP_EOL;
}
