What is the significance of using natsort() with glob() in PHP and how does it affect file sorting?

When using the glob() function in PHP to retrieve a list of files, the default sorting order may not be in natural order. This can lead to unexpected results when sorting files with numerical values in their names. By using the natsort() function in conjunction with glob(), we can ensure that the files are sorted in a natural order, taking numerical values into account. 

$files = glob('path/to/files/*');
natsort($files);

foreach ($files as $file) {
    echo $file . "<br>";
}
