Without knowing more about the application, I can only show you code that is similar to what you want to do.

 

$sellers_count = array();

foreach( $sellers_array as $seller )
{
     if( ! in_array( $seller, $sellers_count ) )
     {
           $sellers_count[] = $seller;
     }
}

$total_unique_sellers = count( $sellers_count );

 

If you simply replace $sellers_array with the actual array of sellers, you should be able to use $total_unique_sellers as your count of unique sellers.
