Question

I have 2 variables: $vatRate and $priceExVat. I want to create another variable named $endPrice which adds the VAT on. I have no clue on how to do this, and am a begginner at PHP so I would like to have a code example 😉

$priceExVat == $_POST['priceExVat'];
$vatRate = $_POST['vatRate'];
rtrim($vatRate ,'%');
$endPrice = ($vatRate * $priceExVat) + $priceExVat;
echo $endPrice;

EDIT: Above is the non-working code which returns a 0

Answer 1

$endPrice = ($vatRate * $priceExVat) + $priceExVat;

or

$endPrice = (1+$vatRate * $priceExVat);

Example

$vatRate = 0.07;
$priceExVat = 100.00;

Since getting -3

All the answer is somehow wrong if the value is string 20%

$endPrice = ((int)$vatRate/100)*$priceExVat)+$priceExVat;
