How can PHP developers transition from using deprecated mysql functions to mysqli or PDO for database interactions?

PHP developers can transition from using deprecated mysql functions to mysqli or PDO by updating their database interaction code to use the newer and more secure mysqli or PDO extensions. This involves updating the connection method, query execution, and result fetching to align with the syntax of mysqli or PDO. By making these changes, developers can ensure their code remains compatible with newer PHP versions and follows best practices for database interactions. 

// Using mysqli
$mysqli = new mysqli("localhost", "username", "password", "database");

if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

$result = $mysqli->query("SELECT * FROM table");

while ($row = $result->fetch_assoc()) {
    // Process each row
}

$mysqli->close();
