Done some searching, but can't seem to find the exact answer I'm looking for.
I'd like to pull in files with numbered filenames using 'scandir($dir)', but have them sort properly. For example, file names are:
1-something.ext
2-something-else.ext
3-a-third-name.ext
.
.
.
10-another-thing.ext
11-more-names.ext
The problem I'm having is that 10-a-fourth-thing.ext will show before 2-something-else.ext. I'd like to find a better way of solving this issue than introducing leading '0' in front of all file names.
Any thoughts? Thanks.
Answer
natsort does exactly what you need.
sort with SORT_NUMERIC will also work for filenames that start with numbers, but it will break if there are also names that have no numbers in front (all non-number-prefixed names will be sorted before number-prefixed names, and their order relative to one another will be random instead of alphabetic).
