How can old fetch styles in PHP be relearned and applied when using PDO?

When transitioning from using old fetch styles in PHP to PDO, it's important to understand that PDO uses a different method for fetching data from a database. To relearn and apply old fetch styles, you can use the PDO fetch methods such as fetch, fetchAll, fetchColumn, etc., which provide similar functionality to the old fetch styles. By familiarizing yourself with these PDO fetch methods, you can effectively retrieve data from a database in a way that is compatible with your previous fetch styles. 

// Example of using PDO fetch methods to retrieve data from a database
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $stmt = $pdo->query("SELECT * FROM mytable");

    // Using fetchAll to retrieve all rows
    $rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

    foreach ($rows as $row) {
        // Access data using associative array keys
        echo $row['column_name'] . "<br>";
    }
} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}
