How can PDO be implemented in PHP to retrieve and process multiple results from a MySQL query?

When using PDO in PHP to retrieve and process multiple results from a MySQL query, you can use a combination of fetchAll() and foreach loop to iterate over the results. This allows you to fetch all rows returned by the query and process each row individually. 

// Assume $pdo is your PDO database connection

$query = $pdo->query("SELECT * FROM table_name");
$results = $query->fetchAll(PDO::FETCH_ASSOC);

foreach($results as $row) {
    // Process each row here
    echo $row['column_name'] . "<br>";
}
