This is *rebuilding* the array from scratch on each "page".

This is *inside* the loop, so shows you the first array, with page 1, and
then the second array, with page 3.
But you never really had an array with *both* pages in it at once.
Change the $pgids = array($pid => $pagename);
line to just:
$pgids[$pid] = $pagename;
Now, since you probably want $pgids to be an array even if there are *no*
pages matching the criteria, insert a line *before* the loop:
$pgids = array();
This will guarantee that $pgids is always an array.

You'll want to reset($pgids) before you use it again.

You need to keep track of which $pgid[] you are on -- Keep a running counter
or something so that after you have $pgids[1] and $mpgids[1], you'll know
that you are on $pgids[3] and $mpgids[2], and then $pgids[3] (still) and
$mpgids[3].
In other words, you need two distinct iterators going in parallel.
