When explode() hit's the "junk" entry, a one element array is going to be
returned when list() is looking for two. So that'll be causing your
warnings.
Why use list?
foreach($data as $value)
{
$part = explode('=',$value);
if(count($part) != 2)
{ echo "array value did not have = sign"; }
else
{
if(isset($arrayvalues[$part[0]]))
...
}
}

You could always just resort to
error_reporting(E_ALL ^ E_NOTICE)
at the beginning of your script and be done with this. :) But that's
cheating.
