If you redeclare the list *outside* the .each block, you'll end up with the
same list. Also if you redeclare it outside, against the $php_remove
array, you'll get something weird.
If you redeclare it *inside* the .each block, it'll be local to that block,
get destroyed on the second run, and you'll end up with a fresh copy for
the next value of your $php_remove array.
You need to make sure you don't reuse variable names so you don't get
confused, but it'll work.
If you want to use the same package list in both places, you may be able to
play some games with single- and double-quoting, but I don't think I'd
recommend that.
