How can PHP be used to store multiple checkbox values in a single column in a SQL database?

When storing multiple checkbox values in a single column in a SQL database, you can serialize the array of selected values before storing it in the database. This way, you can easily retrieve and unserialize the values when needed. 

// Assume $checkboxValues is an array of selected checkbox values
$serializedValues = serialize($checkboxValues);

// Insert $serializedValues into the database
$query = "INSERT INTO table_name (checkbox_column) VALUES ('$serializedValues')";
// Execute the query
```

When retrieving the values from the database, you can unserialize the data to get back the array of checkbox values.

```php
// Retrieve the serialized values from the database
$query = "SELECT checkbox_column FROM table_name WHERE id = 1";
// Execute the query and fetch the result
$result = $pdo->query($query);
$row = $result->fetch();

// Unserialize the values to get back the array of checkbox values
$checkboxValues = unserialize($row['checkbox_column']);
