    Converting an object to an array in PHP can be achieved in several ways. Here are the most common methods:

    1. Using get_object_vars() Function: This function returns an associative array containing all the accessible non-static properties of the specified object. If a class has private or protected properties, they will be included in the output only if the function is called within the class.

      Example:

      $object = new stdClass();
      $object->property1 = 'Value1';
      $object->property2 = 'Value2';
      
      $array = get_object_vars($object);
      print_r($array);
      
    2. Type Casting: In PHP, you can directly cast an object to an array. This method is straightforward but has a limitation: it will include all the properties of the object, including private and protected ones, which might not always be desired.

      Example:

      $object = new stdClass();
      $object->property1 = 'Value1';
      $object->property2 = 'Value2';
      
      $array = (array) $object;
      print_r($array);
      
    3. Using json_encode() and json_decode(): This method involves converting the object to a JSON string and then decoding it back to an array. This is useful when you need a deep conversion (converting objects within objects to arrays).

      Example:

      $object = new stdClass();
      $object->property1 = 'Value1';
      $object->property2 = 'Value2';
      
      $json = json_encode($object);
      $array = json_decode($json, true);
      print_r($array);
      
    4. Using Reflection: This is a more advanced technique, usually used when you need more control over the conversion process, like accessing private and protected properties.

      Example:

      $object = new stdClass();
      $object->property1 = 'Value1';
      $object->property2 = 'Value2';
      
      $reflectionClass = new ReflectionClass($object);
      $properties = $reflectionClass->getProperties();
      $array = array();
      foreach ($properties as $property) {
          $property->setAccessible(true);
          $array[$property->getName()] = $property->getValue($object);
      }
      print_r($array);
      

    Each method has its own use cases and limitations, so the choice depends on the specific requirements of your situation.
