How can you efficiently check if a folder is empty in PHP before attempting to read its contents?

To efficiently check if a folder is empty in PHP before attempting to read its contents, you can use the `scandir()` function to get an array of files and directories within the folder, and then check if the count of this array is equal to 2 (representing the current directory '.' and parent directory '..'). If the count is 2, then the folder is empty. 

$folderPath = 'path/to/folder';

$files = scandir($folderPath);
if(count($files) === 2) {
    echo "Folder is empty.";
} else {
    echo "Folder is not empty.";
}
