如何计算总数？

Question

I am looking for a way to get the sum of a values. I have this <nbsection>2</nbsection><nbsection>4</nbsection>

So I do this loop to get the values of the nbsection but I don't have the sum:

$countvaluesection=0;

foreach($getneb as $clé=>$value){

    $countvaluesection+=$value->nbsection)
    var_dump($countvaluesection)

}

I have on var_dump 2 and 4, not the total. How can I get the total?

Thanks in advance!

Answer 1

That can't be your code because you have multiple syntax errors. This has an end paren without a beginning paren and is missing a semicolon:

$countvaluesection+=$value->nbsection)

This is missing a semicolon:

var_dump($countvaluesection)

This works just fine:

$countvaluesection = 0;

foreach($getneb as $clé => $value){
    $countvaluesection += $value->nbsection;
}

Given that $value has a property nbsection that is a numerical value. Under no circumstances would the value of nbsection be assigned to $countvaluesection when you're using the += operator.
