MasterACE14 Posted September 4, 2010 Share Posted September 4, 2010 Hello, I'm at a total loss, how do I make, for example; 5 pies cost $1, and pies can only be bought in multiple's of 5? Thanks in advance Quote Link to comment Share on other sites More sharing options...
pornophobic Posted September 4, 2010 Share Posted September 4, 2010 Erm... maybe not the best way to do something like this, but it give the option to build outwards, I suppose. function buyPies($amount) { $cost = 1; //cost of a bunch of pies. $units = 5; //Amount of pies in a bunch $costPerUnit = $cost / $units; //Cost of each unit in a group of pies. //Add a function for buying a group of pies? $total = 0; $qty = 0; $total = $total + $cost * $amount; $qty = $qty + $units * $amount; return array('total' => $total, 'quantity' => $qty); } print_r(buyPies(5)); /* Outputs: Array ( [total] => 5 [quantity] => 25 ) */ $arr = buyPies(10); echo $arr['total']; //ouputs 10 echo $arr['qty']; //outputs 50 Quote Link to comment Share on other sites More sharing options...
