Why is it recommended to refer to updated tutorials and resources when learning PHP programming to avoid outdated practices and errors?

It is recommended to refer to updated tutorials and resources when learning PHP programming to avoid outdated practices and errors because PHP is a constantly evolving language with new features, functions, and best practices being introduced regularly. Relying on outdated tutorials can lead to using deprecated functions or insecure coding practices, which can result in errors or vulnerabilities in your code. 

// Example of using an outdated function (mysql_query) that should be avoided
$result = mysql_query("SELECT * FROM users");

// Updated code using mysqli or PDO
$connection = new mysqli($servername, $username, $password, $dbname);
$result = $connection->query("SELECT * FROM users");
