Question

here is my array

Array
(
    [0] => 31
    [1] => 36
    [2] => 41
)

the 31,36, and 41 are id’s of a record. the elements in this array can be from anywhere of 1 element to 10+ elements. the table structure looks something like this (shortened-version)

tbl_cart
---------
id (auto-incremented)
product_name
price

what i’m trying to figure out is how can i do a query that will grab the id’s listen in a dynamically created array then accumulate the price for each respected id and display the output?

thanks, let me know if this doesnt make sense.

Answer 1

you want to sum the prices for the ids in your list right?

$idStr = implode(',', $arr);
$sql = "SELECT sum(price) FROM tbl_cart WHERE id in ($idStr)";
