What are common errors to look out for when using PDO in PHP for database operations?

One common error to look out for when using PDO in PHP for database operations is not properly handling exceptions. It is important to wrap your database operations in a try-catch block to catch any potential errors that may occur during the execution of the query. 

try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    // Perform database operations here
    
} catch(PDOException $e) {
    echo "Error: " . $e->getMessage();
}
