What are the benefits and drawbacks of using Emulated = true versus Emulated = false in PHP PDO Prepared Statements?

When using PDO Prepared Statements in PHP, setting Emulated = true allows PDO to emulate prepared statements if the driver does not support them natively. This can provide better compatibility across different database systems. However, setting Emulated = false ensures that true prepared statements are used, which can offer better security by preventing SQL injection attacks. The drawback of setting Emulated = false is that it may not work with some older database drivers or systems.

// Setting Emulated = false to use true prepared statements
$pdo = new PDO($dsn, $username, $password, array(PDO::ATTR_EMULATE_PREPARES => false));
