What are the best practices for designing a database structure in PHP to efficiently store and retrieve checkbox values?

When storing checkbox values in a database in PHP, it is best to use a separate table to store the values in a normalized structure. This allows for efficient storage and retrieval of checkbox values without duplicating data. Each checkbox value can be stored as a separate row in the table, with a reference to the main record it belongs to. 

// Create a table to store checkbox values
CREATE TABLE checkbox_values (
    id INT AUTO_INCREMENT PRIMARY KEY,
    record_id INT,
    checkbox_value VARCHAR(50)
);

// Insert checkbox values into the table
$record_id = 1;
$checkbox_values = ['value1', 'value2', 'value3'];

foreach ($checkbox_values as $value) {
    $sql = "INSERT INTO checkbox_values (record_id, checkbox_value) VALUES ($record_id, '$value')";
    // Execute SQL query to insert checkbox values into the table
}
