-     * Converts a timezone offset string to a PHP timezone name.

-     * This method takes an offset string (e.g., "+08:00" or "-05:30"), calculates the total offset

+     * This method takes a timezone offset string (e.g., "+08:00" or "-05:30") and computes
+     * the total offset in seconds. It then attempts to map the offset to a standard PHP 
+     * timezone name. If no matching timezone is found, it falls back to returning a 
+     * UTC-based timezone string in the same offset format.
+     *
+     * Examples:
+     * - Input: "+07:00" -> Output: "Asia/Jakarta" (if mapping exists).
+     * - Input: "-05:30" -> Output: "UTC-05:30" (fallback if no mapping exists).
      *
      * @param string $offset The timezone offset string (e.g., "+08:00", "-05:30").
-     * @return string The PHP timezone name, or a fallback UTC offset string.
+     * @return string The corresponding PHP timezone name, or a fallback UTC offset string (e.g., "UTC+08:00").
