What is the significance of setting PDO::ATTR_EMULATE_PREPARES to false when using PDO Prepared Statements?

Setting PDO::ATTR_EMULATE_PREPARES to false ensures that PDO uses real prepared statements, which can help prevent SQL injection attacks and improve performance by allowing the database to optimize query execution. Emulated prepared statements can lead to security vulnerabilities if not handled properly, so it is recommended to disable them when using PDO Prepared Statements. 

// Set PDO::ATTR_EMULATE_PREPARES to false
$pdo = new PDO($dsn, $username, $password);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
