What is the recommended alternative to the deprecated feature in PHP?

The recommended alternative to the deprecated feature in PHP is to use the newer and more secure functions or methods provided by PHP. This ensures that your code remains up-to-date and compatible with future versions of PHP. It is important to regularly check the PHP documentation for any deprecated features in your code and replace them with the recommended alternatives.

$newVar = mysqli_query($conn, "SELECT * FROM table");
