Add values from a php string

Question

I have the following code:

foreach ($class->ListaChave($CdLote) as $dados) {
   var_dump($dados->getQvol());
}

Exit:

string(1) "1"

string(1) "1"

string(1) "2"

string(1) "1"

I need these values to be summed up and returned to me the value within a variable.

Answer 1

You can make the sum normally. But if you want to ensure that the return of getQVol() always be whole, and do not have access to class to change, you can do so:

<?php
$soma = 0;
foreach ($class->ListaChave($CdLote) as $dados) {
   $soma += (int) $dados->getQvol();
}

echo $soma;
