 * 標題：如何將timezone_location_get函數與date()函數結合，獲取並格式化正確的時間？
 *
 * 在PHP中，處理時區相關的時間數據時，準確獲取時區位置信息並正確格式化時間是非常重要的。本文將介紹如何利用PHP內置的
 * timezone_location_get()函數配合date()函數，獲取時區對應的地理位置坐標，並最終輸出格式化的時間字符串。
 *
 * 一、了解timezone_location_get()
 * timezone_location_get()函數接受一个DateTimeZone對像作為參數，返回該時區的地理位置信息，包括經度（longitude）、緯度（latitude）、國家代碼（country_code）等。
 *
 * 語法示例：
 * $tz = new DateTimeZone('Asia/Shanghai');
 * $location = timezone_location_get($tz);
 * var_dump($location);
 *
 * 二、結合date()函數格式化時间
 * date()函數用于格式化時间戳，生成易讀的時間字符串。為了保證時間的準確性，需先用DateTime設置正確的時區，再調用format()方法。
 *
 * 三、完整示例代碼

 * 四、小結
 * 1. timezone_location_get()提供時區的地理信息，方便了解該時區對應的區域。
 * 2. 結合DateTime和DateTimeZone，可以確保時間格式化時的時區準確。

 * 通過本文方法，您可以更精準地處理和顯示不同時區的時間數據。
