variables inside single quotes are not evaluated! This is the same variable:
echo $GLOBALS['var'];
$key='var'; echo $GLOBALS[$key];
With $GLOBALS['$key'] you refer to an invalid variable name $'$key'
PS: Output of
echo "GLOBALS['$key'] = $value\n";
is right because $key is in double quotes (the outermost qoutes)

$GLOBALS[$key] is incorrect and depricated AFAIK.
$GLOBALS['$key'] (with the single quotes) is the proper way to write these
types of associative arrays/hashs.
For shits and giggles however I tried your way and it made no difference to
the code. Still didn't work right.

function clearContactVars()

foreach ($GLOBALS as $key => $value) {
if ( substr($key,0,8) == "contact_" ) {
//echo "GLOBALS['$key'] = $value\n";
$GLOBALS['$key'] = "";
I did not read your whole message, but you very likely mean
$GLOBALS[$key] = "";
(no single quotes)
}
}
clearPostVars();
}
