What are the differences between using exec() and execute() in PDO for executing queries in PHP?

When executing queries in PDO in PHP, it's important to note that there is no `exec()` method in PDO. The correct method to execute queries in PDO is `execute()`. Using `exec()` will result in an error as it is not a valid method in PDO. Therefore, always use `execute()` when executing queries in PDO to ensure proper functionality. 

// Incorrect method using exec()
$stmt = $pdo->prepare("SELECT * FROM table");
$stmt->exec(); // This will result in an error

// Correct method using execute()
$stmt = $pdo->prepare("SELECT * FROM table");
$stmt->execute(); // This will properly execute the query
