php - 2 decimal places?

[7724]

Hi,

I've created an IF statement:

<? 
if ($type_class =="Economy") { 
    $ticket_cost = 150; 
    }     

if ($type_class =="Business") { 
    $ticket_cost = 200; 
    }       

if ($type_class =="First Class") { 
    $ticket_cost = 300;      

    }                          

    $air_total = $tickets * $ticket_cost;                               // calculate tickets * ticket cost 
    $air_tax = ($air_total * 17.5)/100;                                 // calculate VAT on total 
    $overall_total = $air_total + $air_tax;                             // calculate total price with VAT 
?> 

Which outputs a total ticket cost, tax cost and overall total. How do I enable these results to be shown to 2 decimal places?

Thanks

Chris
