Sum of an array

[Anon]

Does anyone know a way of summarizing the values within an array

i've got several value like:

$number[1]
$number[2]

etc

the array_sum($number)

does not work

error message:The argument to array_sum() should be an array

thanks

How did you declare/initialize $number?

using if statements (not the most elegant way of doing it:

$number=0;

$pricetransfer1=round($pricetransfer1,2);

if ($numbertransfer1$pricetransfer1>0)
{
$number++;
$priceorder[$number]=$pricetransfer1;
$nameorder[$number]=$nametransfer1;
$numberorder[$number]=$numbertransfer1;
$amountorder[$number]=$numbertransfer1$pricetransfer1;
}

if ($numbertransfer2*$pricetransfer2>0)
{

$number++;
$priceorder[$number]=$pricetransfer2;
$nameorder[$number]=$nametransfer2;
$numberorder[$number]=$numbertransfer2;
$amountorder[$number]=$numbertransfer2*$pricetransfer2;
$amountorder=round($amountorder,2);

and so on
