Electronics 2 times

How it will possible ?

Answer 1

Something like this might work:

select c.cat, count(t.answer)
from (select 'cloths' as cat union all
      select 'electronics' union all
      select 'food'
     ) c left outer join
     table t
     on t.answer like concat('%', c.cat, '%')
group by c.cat;

Answer 2

Maybe something like this in PHP?

$options    = array('Cloths','Electronics', 'food');
$values     = array();
foreach($options as $option)
{
    $total = mysql_num_rows("SELECT * FROM TBL_SHOPPING WHERE answer '%".$option."%'");
    $values[$option] = $total;
}

Note that you should use mysqli or PDO instead of the original MySQL API.
