How can the getDir() function be modified to display the directory entries in a sorted order?

The issue can be solved by modifying the getDir() function to retrieve the directory entries and then sort them before displaying them. This can be achieved by using the scandir() function to get the directory entries, sorting the entries using the sort() function, and then looping through the sorted entries to display them.

function getDir($dir){
    $entries = scandir($dir);
    sort($entries);
    
    foreach($entries as $entry){
        if($entry != '.' && $entry != '..'){
            echo $entry . "<br>";
        }
    }
}

// Example usage
getDir('/path/to/directory');
