make sure if you're serializing arrays for posting via a form that you 
base64_encode/decode them. The serialized string otherwise contains 
quotations that will mess up your form and add/stripslashes doesn't work.

be careful when using array_unique as it *does not* sort out the key 
increment. so if you subsequently use the array in a for loop referenced by 
indices, you'll experience weird results!

instead use: (from user submitted comment on php.net)

function my_array_unique($array){
     $tmparr = array_unique($array);
     $i=0;
     foreach ($tmparr as $v) {
         $newarr[$i] = $v;
         $i++;
     }
     return $newarr;
}

</tip>
