Adding a looped value

[Anon]

OK I have cookie which is holding the values $cat_id which repersents and item stored in a database (MySQL) and the value $qty. using the $cat_id stored in the cookie, I use it to pull the value $price from the database and the value $qty. so if a user chooses 3 items the cookies is holding three $cat_id so I have three $price and three $qty.
I take these values and multiply them...

$s_total = $row[price] * $qty;

so if I disply them it looks like this

| price |qty|total

1.| 23.00 | 2 |46.00
2.| 33.00 | 1 |66.00
3.| 21.00 | 1 |42.00

What I want to do is add the $s_totals together to get a grand total. how can I do this.

Hope that clear.
TIA

foreach ($array as $value) {

$sum += $value;

}

$sum now equals the total of all $value's. Also, a function called array_sum() now exists (as of 4.0.4) that does the same thing (although it is undocumented as of right now).
