I'm not sure what's causing that error.

<?php
if (!in_array($HTTP_POST_VARS['pid']['pid'], $_SESSION['pid']))
{
    //echo $HTTP_POST_VARS['pid']['pid'].\"here\";
    $_SESSION['pid'][] = $HTTP_POST_VARS['pid']['pid'];
}


// that is the hard way to force a unique PID
// it's easier to just put everything into your array,
// then use array_unique()
$_SESSION['pid'][] = $HTTP_POST_VARS['pid']['pid'];
$_SESSION['pid'] = array_unique($_SESSION['pid']);
?>
