I was thinking it was obvious because otherwise I'd have just been using
that and not even posted about the "a/a+".  Using "a" works in the way that
it is supposed to (it starts at the end), but what I wanted was to use
append and then just append to anywhere in the file.

Currently to get that done I use "file(filelocation);" and then just search
that array for what I want.  Once I find it I save the key and then
concatenate what I want to that line.  Then after I've done that I implode
the array and "w" (write) that.   This of course works perfectly, but once
the file starts to get larger, I'm worried that it is going to become slow,
so I was looking for a way to append (which now that I think about it, would
do the same thing, only with less work on my part).
