When should natsort() be used instead of sort() for sorting file names in PHP?

When sorting file names in PHP, natsort() should be used instead of sort() when you want a more natural sorting order. natsort() is a natural sorting algorithm that treats numbers in file names as numeric values, rather than strings. This means that file names containing numbers will be sorted in a more human-readable way, such as "file1.txt" before "file10.txt". 

$files = scandir('/path/to/directory');
natsort($files);

foreach ($files as $file) {
    echo $file . "\n";
}
