How can I check for the absence of a specific file extension in a folder using PHP?

To check for the absence of a specific file extension in a folder using PHP, you can use the `glob` function to retrieve an array of files with a specific extension, and then check if the array is empty. If the array is empty, it means that there are no files with that specific extension in the folder. 

$files = glob('path/to/folder/*.extension');

if (empty($files)) {
    echo 'No files with the specified extension found in the folder.';
} else {
    echo 'Files with the specified extension found in the folder.';
}
