How can database version compatibility issues be addressed when exporting and importing databases in PHP?

Database version compatibility issues can be addressed when exporting and importing databases in PHP by ensuring that the SQL queries used are compatible with the target database version. This can involve checking for any deprecated features or syntax that may cause errors in the new version. Additionally, using database abstraction layers or ORM libraries can help in managing database version differences. 

// Example code using PDO with prepared statements to ensure compatibility with different database versions
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $stmt = $pdo->prepare("SELECT * FROM mytable");
    $stmt->execute();

    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        // Process the data
    }
} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}
