How can data be grouped and sorted alphabetically in PHP for display on a webpage?

To group and sort data alphabetically in PHP for display on a webpage, you can use the `usort` function along with a custom comparison function. This function will compare the values of two elements and sort them alphabetically. You can then loop through the sorted data and display it on the webpage. 

// Sample data array
$data = array("Apple", "Banana", "Orange", "Grapes");

// Custom comparison function for sorting alphabetically
function custom_sort($a, $b) {
    return strcmp($a, $b);
}

// Sort the data array alphabetically
usort($data, "custom_sort");

// Loop through the sorted data and display on the webpage
foreach ($data as $item) {
    echo $item . "<br>";
}
