What are the implications of not having a unique identifier for each record in a MySQL table when dealing with multilingual data in a PHP application?

Without a unique identifier for each record in a MySQL table, it can be challenging to properly manage and update multilingual data in a PHP application. This can lead to issues such as duplicate entries or difficulties in retrieving and displaying the correct data for each language. To solve this issue, it is important to have a unique identifier for each record in the table to ensure accurate and efficient handling of multilingual data. 

// Ensure the table has a unique identifier column (e.g. id)
// Use the unique identifier to retrieve and update the correct multilingual data

// Example query to retrieve multilingual data based on unique identifier
$query = "SELECT * FROM table_name WHERE id = :id";
$stmt = $pdo->prepare($query);
$stmt->execute(['id' => $record_id]);
$record = $stmt->fetch();

// Example query to update multilingual data based on unique identifier
$query = "UPDATE table_name SET column_name = :value WHERE id = :id";
$stmt = $pdo->prepare($query);
$stmt->execute(['value' => $new_value, 'id' => $record_id]);
