How to read a PHP variable as a numeric variable to make some calculation?

I am having problems with a variable which reads 17,50 for calculation. The variable is part of an array and i am just getting the value 17.00

$product_price_tmp = intval(str_replace(",",".",$custom_values['product_price'][0]));

and i tried the following

$product_sub_total = sprintf("%.2f",$product_price_tmp);//reads 17.00
$product_sub_total = $product_price_tmp;//reads 17

I didn't notice the problem as all my test price values were rounded numbers.

Any tips?

You don't need intval since it is not int you intend to get. It is enough to cast float type here:

$product_price_tmp = (float) str_replace(",",".",$custom_values['product_price'][0]);
var_dump($product_price_tmp);

//float 17.5

Replace this 

$product_price_tmp = intval(str_replace(",",".",$custom_values['product_price'][0]));

with this 

$product_price_tmp = floatval(str_replace(",",".",$custom_values['product_price'][0]));
