How can server hardware specifications impact the speed of selecting entries from a large database table using PHP?

Server hardware specifications such as CPU speed, RAM size, and disk type can impact the speed of selecting entries from a large database table using PHP. To improve performance, consider upgrading to a server with a faster CPU, more RAM, and a solid-state drive (SSD) for faster disk access. 

// Example code snippet using PHP PDO to connect to a MySQL database and select entries from a large table
$dsn = 'mysql:host=localhost;dbname=mydatabase';
$username = 'username';
$password = 'password';

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

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

    foreach ($results as $row) {
        // Process each row as needed
    }

} catch (PDOException $e) {
    echo 'Error: ' . $e->getMessage();
}
