How can PHP beginners effectively organize data from a MySQL table into arrays for better manipulation?

To effectively organize data from a MySQL table into arrays for better manipulation, beginners can use PHP's mysqli or PDO extension to connect to the database, execute a query to fetch the data, and then store the results in an array for easy manipulation. This can be achieved by looping through the fetched data and adding each row to an array. 

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// Query to fetch data from MySQL table
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

// Store fetched data in an array
$data = array();
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $data[] = $row;
    }
}

// Close database connection
$conn->close();

// Manipulate the data stored in the array
foreach ($data as $row) {
    // Manipulate each row of data here
}
