How can PHP beginners ensure they are using up-to-date and secure coding practices, especially when learning from older resources?

PHP beginners can ensure they are using up-to-date and secure coding practices by regularly checking for updates to the PHP language and popular frameworks, using secure coding practices recommended by PHP security experts, and avoiding deprecated functions or features. When learning from older resources, beginners should cross-reference information with official PHP documentation and online resources to ensure they are following current best practices. 

// Example of using up-to-date and secure coding practices in PHP
// Avoid using deprecated functions like mysql_connect
// Instead, use mysqli or PDO for database connections

// Connect to a MySQL database using mysqli
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
