How can natsort() and sort() functions in PHP be used to sort directories or files in a specific order?

When sorting directories or files in PHP, the natsort() function can be used to sort them in a natural order (e.g., file1.txt, file2.txt, file10.txt) while the sort() function sorts them in a standard alphabetical order (e.g., file1.txt, file10.txt, file2.txt). To sort directories or files in a specific order, you can use natsort() to achieve a natural sort order.

// Get a list of files in a directory
$files = scandir('path/to/directory');

// Use natsort() to sort the files in a natural order
natsort($files);

// Loop through the sorted files
foreach ($files as $file) {
    echo $file . "<br>";
}
