oscommerce shooping cart tax class id select

[zeberrun]

$shopping_card_products = $cart->get_products();
    for ($i=0, $n=sizeof($shopping_card_products); $i<$n; $i++) {
		echo $shopping_card_products[$i]['id'] . '<br/>';		
	$result= tep_db_query("select products_tax_class_id from " . TABLE_PRODUCTS . " where products_id = '".$shopping_card_products[$i]['id']."'");
	  while ($get = tep_db_fetch_array($result)){

 echo '------ ' . $get['products_tax_class_id'] . ' <br />';
}
    }

i have 3 products_tax_class_id value for shopping_card_products.
the result comes like this
5 --- 1,
6 --- 2,
7 --- 2,
8 --- 3,
9 --- 1, ...
sometimes
i can decrease of increase shopping_card_products
than the result comes like this
6 --- 2,
7 --- 2, ..

now i want to write if close,

if (there is not any 3 value in results ) { do this} else { there is any 3, do that}

how can i write ?

Well, look through the results, and if there is a 3 in there, do something, and if there isn't, do something else.

You've pretty much said yourself how to do it. So what have you tried? (Hint: you might want to have the results in an array.)

first of all i want to pass second condition. if ... {first condition} else {second condition}. i should check

products_tax_class_id's of products, if there is not any 3, do the second condition,else do the first condition.

since the code flow follows ths order.

3 items in card, products_tax_class_id = 1, products_tax_class_id = 2, products_tax_class_id = 3

if ($get['products_tax_class_id'] != 3 )[code=php]
goes first condition, result 1, 2, two rows.

2 items in card, products_tax_class_id = 1, products_tax_class_id = 22
[code=php]if ($get['products_tax_class_id'] != 3 )[code=php]
goes first condition, result 1, 2, two rows.

2 items in card, products_tax_class_id = 1, products_tax_class_id = 2
[code=php]if ($get['products_tax_class_id'] = 0 )[code=php]
goes second condition, result 1, 2 two rows. values 0

all the rows are coming, i should only select products_tax_class_id 3 from the results, i was thinking about.

2 items in card, products_tax_class_id = 1, products_tax_class_id = 2

if ($get['products_tax_class_id'] == 3 )

goes second condition, result 1, 2, two rows.

if ($get['products_tax_class_id'] == 0 )

goes second condition, result 1, 2, 3 three rows.

2 items in card, products_tax_class_id = 1, products_tax_class_id = 2

if ($get['products_tax_class_id'] == 0 )

goes second condition, result 1, 2 two rows.

2 items in card, products_tax_class_id = 1, products_tax_class_id = 2

if (($get['products_tax_class_id'] == 1 ) || ($get['products_tax_class_id'] == 2 ))

goes first condition, result 1, 2 two rows.

3 items in card, products_tax_class_id = 1, products_tax_class_id = 2, products_tax_class_id = 3

if (($get['products_tax_class_id'] == 1 ) || ($get['products_tax_class_id'] == 2 )) 

goes first and second condition, result 1, 2, 3 three rows.

all the values are returning, whereas i need products_tax_class_id 3 from the results.
