Ne razumem ovaj deo:
.number_format($totalamount,2). sta ovo znaci znam da je totalamount promenjljiva, ali sta je ovo number_format, i ne razumem zasto ova 2 stoji iza zareza, koja je njena funkcija ?
I jos ovo:
$totalamount = $totalamount * (1 + $taxrate); Zasto se nalazi 1+ ispred $taxrate ?
Mozda ovo vama izgleda glupo il smesno, al poceo sam sa phpom juce pa mi ovo jos nije jasno, hvala unapred svima
