What is the significance of migrating from the MySQL extension to MySQLi or PDO in PHP 5.5 and how can beginners adapt to this change?

Migrating from the MySQL extension to MySQLi or PDO in PHP 5.5 is significant because the MySQL extension is deprecated and no longer supported in PHP 5.5 and above. This change is necessary to ensure compatibility, security, and performance improvements in your PHP applications. Beginners can adapt to this change by updating their code to use MySQLi or PDO for database connections and queries. 

// Using MySQLi extension for database connection
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

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

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

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"] . " - Name: " . $row["name"];
    }
} else {
    echo "0 results";
}

$mysqli->close();
