What are the potential pitfalls of using deprecated MySQL functions in PHP, as seen in the code provided?

Using deprecated MySQL functions in PHP can lead to security vulnerabilities, compatibility issues with newer versions of MySQL, and potential errors or warnings in your code. It is recommended to switch to MySQLi or PDO for database operations to ensure better security and future-proof your code. 

// Deprecated MySQL functions example
$connection = mysql_connect("localhost", "username", "password");
mysql_select_db("database_name", $connection);
$result = mysql_query("SELECT * FROM table_name", $connection);
while ($row = mysql_fetch_assoc($result)) {
    // Process data
}

// Updated code using MySQLi
$connection = mysqli_connect("localhost", "username", "password", "database_name");
$result = mysqli_query($connection, "SELECT * FROM table_name");
while ($row = mysqli_fetch_assoc($result)) {
    // Process data
}
mysqli_close($connection);
