How can PHP be used to sort multiple columns, including names and points per game day?

To sort multiple columns, including names and points per game day, in PHP, you can use the array_multisort() function. This function allows you to sort multiple arrays or multidimensional arrays based on one or more columns. You can specify the sorting order (ascending or descending) for each column. 

// Sample data with names and points per game day
$data = [
    ['name' => 'Alice', 'points' => 20],
    ['name' => 'Bob', 'points' => 15],
    ['name' => 'Charlie', 'points' => 25],
];

// Separate the columns into their own arrays
$names = array_column($data, 'name');
$points = array_column($data, 'points');

// Sort the data by points (descending) and then by names (ascending)
array_multisort($points, SORT_DESC, $names, SORT_ASC, $data);

// Output the sorted data
foreach ($data as $row) {
    echo $row['name'] . ' - ' . $row['points'] . '<br>';
}
