it appears to be parameter expansion -- see that same html,
search on ${parameter#word}, but because the '#' is escaped it
looks like an error to me, and gives a 'bad substitution'
error if i try to echo that thing on the command line
of course i am using a bash command line, and you mention Mac
and xampp, which makes me wonder if looking at bash manuals is
the appropriate place to look
for all i know mac has their own flavor of shell that's
disturbingly different from linux bash
which is all a long winded way of saying i dunno, sorry
