How do i add the values(which are prices) in an array?

If the price is just a number (i.e. 5.50), then you can just loop 
through the array and add them.  However, if there's a something like a 
dollar sign in the price (i.e. $4.25), you'll have to extract the 
number, before adding.
This sample function will account for both possibilities by simply 
stripping any character that doesn't make-up a number from the
array value.  Not fool-proof, but should work for most cases.
function array_sum( $array ) {
    $total = 0;
    foreach ($array as $value)
        $total += ereg_replace("[^0-9.-]+", "", $value);
    return $total;
}
