What are some alternative approaches to checking if a folder is empty in PHP, aside from using the glob() function?

One alternative approach to checking if a folder is empty in PHP is to use the opendir() and readdir() functions to iterate through the files in the folder. If no files are found, then the folder is considered empty. 

$folder = 'path/to/folder';

$handle = opendir($folder);

// Check if the folder is empty
if (!$handle || count(scandir($folder)) == 2) {
    echo "Folder is empty";
} else {
    echo "Folder is not empty";
}

closedir($handle);
