@tolgahanacar You cannot multiply these operands. What result would you expect
"USD"
* "1" to be? What exactly your application is supposed to do when the operands
aren't what you expect them to be, only you can know.
```php
$currency = json_decode(file_get_contents('https://api.example.com/embed/currency.json'),
true);
$value = filter_var($_POST['value'], FILTER_VALIDATE_INT);
$usd = filter_var($currency['USD']['sale'], FILTER_VALIDATE_INT);
if ($value === false || $usd === false) {
// Do something else
}
echo $value * $usd;
```
