Just for the record: df -Ph is a bit schizophrenic, because -P asks for output in POSIX-format and -h asks for output in "human readable" format (whatever that may be in Linux, i personally find the changing units annoying, but that is probably personal taste).
For portable scripts it is recommended to only use -P and to parse the output it generates. This will be the same not only in different versions of Linux but also other (POSIX-compliant) UNIX-systems.
I hope that helps.

The records will be printed without any parsing.
