I have MySQL table called products and in this table I have data: 

id | category | product1 | price1 | discount1 | product2 | price2 | discount2 | product3 | price3 |discount3 |
----------------------------------------------------------------------------------------------------------
| 1 | Meat    | Pork 1kg | 3.99   | -30%    | Lamb 1kg    | 5.94 | -25%      | Ham 200g    | 1.99 | -10% |
| 2 | Fruit   | Apple 1kg| 1.25   | -32%    | Banana 1 kg | 0.99 | -15%      | Melon 1 kg  | 0.79 | -12% |

PHP search script I have looks like this:

//-query the database table
$sql="SELECT id, category, product1, price1, discount1, 
product2, price2, discount2, product3, price3, discount3 
FROM products 
WHERE 
product1 LIKE '%" . $name . "%' OR 
price1 LIKE '%" . $name ."%' OR 
discount1 LIKE '%" . $name ."%' OR 
product2 LIKE '%" . $name ."%' OR 
price2 LIKE '%" . $name ."%' OR 
discount2 LIKE '%" . $name ."%' OR 
product3 LIKE '%" . $name ."%' OR 
price3 LIKE '%" . $name ."%' OR 
discount3 LIKE '%" . $name ."%'";

//-run the query against the mysql query function
$result=mysql_query($sql);

//-create while loop and loop through result set
while($row=mysql_fetch_array($result)){

$id=$row['id'];
$category =$row['category'];
$product1=$row['product1'];
$price1=$row['price1'];
$discount1=$row['discount1'];
$product2=$row['product2'];
$price2=$row['price2'];
$discount2=$row['discount2'];
$product3=$row['product3'];
$price3=$row['price3'];
$discount3=$row['discount3'];

//-display the result of the array

echo "<ul>\n"; 
echo  "<li>" . $id . "</li>\n"; 
echo "<li>" . $category . "</li>\n";
echo "<li>" . $product1 . "</li>\n"; 
echo "<li>" . $price1 . "</li>\n";
echo "<li>" . $discount1 . "</li>\n";
echo "<li>" . $product2 . "</li>\n";
echo "<li>" . $price2 . "</li>\n";
echo "<li>" . $discount2 . "</li>\n";
echo "<li>" . $product3 . "</li>\n";
echo "<li>" . $price3 . "</li>\n";
echo "<li>" . $discount3 . "</li>\n";
echo "</ul>";
}

The problem is that when I search for let’s say Apple, Banana and Melon are also displayed.

How can I make it to show only Apple and it’s price and discount when searching with keyword apple.

    Your DB structure is very odd, which is giving you this headache. Instead use normal relations.

    Table categories

    id  name
1   Meat
2   Fruit

    Table products

    id  category_id  product      price  discount
1   1            Pork 1kg     3.99   -30%
2   1            Lamb 1kg     5.94   -25%
3   1            Ham 200g     1.99   -10%
4   2            Apple 1kg    1.25   -32%
5   2            Banana 1 kg  0.99   -15%
6   2            Melon 1 kg   0.79   -12%

    You can find a product (eg ‘pork’) using this query

    SELECT product.*, category.name as category FROM product INNER JOIN category ON product.category_id = category.id WHERE product.name LIKE 'pork%'
