New to PHP, need a little guidance

I'd suggest getting more familiar with the basics of PHP if this has been confusing you. It seems you aren't too keen on how arrays and foreach() work quite yet.

Code:

$follow_ids = array();
$total = 0;

foreach ($query->result_array() as $row)
{
$follow_ids[] = $row['follow_id'];
$total += $row['total'];
}

$variables = array(
array(
  'follow_ids' => implode('|', $follow_ids),
  'total'   => $total
)
);
