What is the significance of the PDO Exception in PHP and how does it affect database connectivity?

The PDO Exception in PHP is significant because it indicates an error in connecting to a database using PDO (PHP Data Objects). This exception can occur due to various reasons such as incorrect credentials, server issues, or database connectivity problems. To handle this exception, you can use try-catch blocks to catch the PDO Exception and handle it gracefully in your code. 

try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    // Other database operations
} catch (PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
