What are the differences between using natsort and sort with SORT_NUMERIC in PHP when sorting arrays of file names?

When sorting arrays of file names in PHP, using natsort will sort the files in a more human-friendly way, taking into account numbers in the file names. On the other hand, using sort with SORT_NUMERIC will sort the files based on numeric value only, ignoring any non-numeric characters in the file names. Depending on the specific requirements of the sorting, either natsort or sort with SORT_NUMERIC can be used to achieve the desired result.

// Using natsort to sort file names in a human-friendly way
$fileNames = ['file1.txt', 'file10.txt', 'file2.txt'];
natsort($fileNames);
print_r($fileNames);

// Using sort with SORT_NUMERIC to sort file names based on numeric value only
$fileNames = ['file1.txt', 'file10.txt', 'file2.txt'];
sort($fileNames, SORT_NUMERIC);
print_r($fileNames);
