How can developers update their code to use mysqli or PDO instead of the deprecated mysql extension in PHP?

The deprecated mysql extension in PHP has been removed from the latest versions of PHP, so developers need to update their code to use either the mysqli or PDO extensions for interacting with databases. To update the code, developers should replace all instances of mysql functions with their mysqli or PDO equivalents. This includes updating connection, query, and result fetching functions. 

// Replace mysql connection with mysqli connection
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

// Replace mysql query and result fetching with mysqli
$result = $mysqli->query("SELECT * FROM table");
while ($row = $result->fetch_assoc()) {
    // Process each row
}
