If you want to get the posts with that category

$myposts = get_posts(array(
'p' => $pid,
'posts_per_page' => -1,
'post_type' => 'post',
'category__in' => array( 4 ),
'post_status' => 'publish',
'author' => $value[0],
));

If you want to get the posts without that category

$myposts = get_posts(array(
'p' => $pid,
'posts_per_page' => -1,
'post_type' => 'post',
'category__not_in' => array( 4 ),
'post_status' => 'publish',
'author' => $value[0],
));
