How does setting ATTR_EMULATE_PREPARES to false in PDO affect memory usage and query execution compared to mysqli?

Setting ATTR_EMULATE_PREPARES to false in PDO can improve memory usage and query execution compared to mysqli because it allows PDO to use native prepared statement support provided by the database driver. This can lead to better performance and reduced memory overhead as the database server can optimize query execution plans more efficiently.

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