Thank you for clearing up my rather lame explanation.
So how can I process $_POST[dynamic-name][user-entered-value] arrays to give
me my desired output:
fname0 = value flab0 = value fplc0 = value
fname1 = value flab1 = value fplc1 = value
fname2 = value flab2 = value fplc2 = value
Any help our example will be most appreciated.

Sorry to be pedantic, but, no, they are generating arrays called fname,
flab, and fplc. The elements of these arrays are fname[0], fname[1],
fname[2]..., flab[0], flab[1]... etc.

This describes one way of handling the arrays:

... but this illustrates exactly the opposite way of treating them:

So which is it you want? Presumably, your example output is correct and the
description is wrong, and what you really want to do is address the first
element of each array, then the second element of each array, and so on. In
which case, you've pretty much described how to do it in your example
output, and your only remaining problem is how to find out how long the
arrays are -- for which I recommend you take a look at
http://www.php.net/count.
Cheers!
