You're sorting characters in the PHP script instead of numbers!
sort(as.character(o)) in R will yield the same results as you PHP script
does.

Do not put your faith in what statistics say until you have carefully
considered what they do not say. ~William W. Watt
A statistical analysis, properly conducted, is a delicate dissection of
uncertainties, a surgery of suppositions. ~M.J.Moroney
