What are some best practices for storing MySQL query results in arrays in PHP for further processing or visualization, such as with PHPlot?

When storing MySQL query results in arrays in PHP for further processing or visualization, it is best practice to use a while loop to fetch each row from the result set and store it in an array. This allows you to easily access and manipulate the data later on. Additionally, you can use PHP functions like mysqli_fetch_assoc() or mysqli_fetch_array() to fetch rows as associative arrays or numeric arrays, respectively. 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

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

// Initialize an empty array to store the results
$data = array();

// Fetch rows and store them in the array
while ($row = $result->fetch_assoc()) {
    $data[] = $row;
}

// Close the connection
$mysqli->close();

// Now $data contains the query results in an array for further processing or visualization
