What is the best practice for storing multiple dropdown field values in a single MySQL cell using PHP?

Storing multiple dropdown field values in a single MySQL cell can be achieved by serializing the values into a string before storing them and then unserializing them when retrieving the data. This allows multiple values to be stored in a single cell and easily retrieved and manipulated in PHP. 

// Serialize dropdown values before storing in MySQL
$values = ['option1', 'option2', 'option3'];
$serializedValues = serialize($values);
$query = "INSERT INTO table_name (dropdown_values) VALUES ('$serializedValues')";
// Execute the query

// Unserialize dropdown values when retrieving from MySQL
$query = "SELECT dropdown_values FROM table_name WHERE id = 1";
$result = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($result);
$unserializedValues = unserialize($row['dropdown_values']);
// Use $unserializedValues array for further processing
