when you are comparing
array1 = array ("blue", "red", "green", "yellow");
array2 = array ("blue", "orange", "white", "yellow",
"black");
$result = array_diff($array2, $array1);
you get back
$result[0] = "";
$result[1] = "orange";
$result[2] = "white";
$result[3] = "";
$result[4] = "black";
odd huh.. and if you are depending on seeing if you got any thing back from both arrays.. then the
best thing to do is to count($result); and go from there..
