How can error reporting in PDO be activated to troubleshoot issues with data insertion?

To activate error reporting in PDO to troubleshoot issues with data insertion, you can set the error mode to `PDO::ERRMODE_EXCEPTION`. This will throw exceptions when errors occur during database operations, providing more detailed information about the issue.

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    // Perform data insertion operations here
    
} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}
