In what scenarios would the fileXtime functions in PHP be more suitable for monitoring changes in directories compared to individual files?

When monitoring changes in directories, using fileXtime functions in PHP would be more suitable compared to individual files when you need to track changes across multiple files within a directory. This is because the fileXtime functions allow you to retrieve the latest modification time of a directory, which can indicate if any file within the directory has been added, removed, or modified. 

$directory = '/path/to/directory';

$latestModificationTime = 0;

$files = scandir($directory);

foreach($files as $file){
    if(is_file($directory.'/'.$file)){
        $fileModificationTime = filemtime($directory.'/'.$file);
        if($fileModificationTime > $latestModificationTime){
            $latestModificationTime = $fileModificationTime;
        }
    }
}

echo "Latest modification time of files in directory: " . date('Y-m-d H:i:s', $latestModificationTime);
