problem with if statement help

[ehpratah]

guys i'm having a really big problem right now..im trying to make a conditional statement using php but im having an logical error or syntax error..im trying to compute for the car rate but im not getting a correct output

e.g

i have a list of car which are "Small Car" "Innova" "Van" and there prices will depend on the location if the location is let say "Manila" or "Cam Sur" or "Boracay" then
Small Car price is 550.00
Innova price is 700.00
Van price is 1000.00

here is the code

<?php
 $vehicle;
      $rhr;
    $phr;
    $total;
    $totalhr;
    $rday;
    $pday;
    $totald;
    $totalday;
    $rmonth;
    $pmonth;
    $totalm;
    $totalmonth;
 
 
if($origin=="NAIA 1" && $vehicle=="Small Car" && $destination=="Manila" || $destination=="Cam Sur" || $destination=="Boracay" )
{
    $perday=3000;
    $permonth=9000;
    $perhour=125;
    $car=1740;
 
if($rhr>$phr)
        {
        $total=($rhr)- ($phr);
        $totalhr=$perhour * $total;
 
        }
    else if($rhr==$phr)
        {    
        $totalhr;
        }
    if($rday>$pday)
        {
        $totald=($rday)-($pday);
        $totalday=$perday * $totald;
        }
    else if($rday==$pday)
        {
        $totalday;
        }
 
    if($rmonth>$pmonth)
        {
        $totalm=$rmonth-$pmonth;
        $totalmonth=$totalm * $permonth;
 
        }
    else if($rmonth==$pmonth)
        {
        $totalmonth;
        }
        $rate=$car+$totalhr+$totalday;     
}
if($origin=="NAIA 1" && $vehicle=="Innova" && $destination=="Manila" || $destination=="Cam Sur" || $destination=="Boracay" )

in that code the "or" "||" condtion is not working please need help...

you should probabley change lines like this:

if($origin=="NAIA 1" && $vehicle=="Small Car" && $destination=="Manila" || $destination=="Cam Sur" || $destination=="Boracay" ) 

to

if($origin=="NAIA 1" && $vehicle=="Small Car" && ( $destination=="Manila" || $destination=="Cam Sur" || $destination=="Boracay" ) ) 

Because '&&' has higher precedence than '||'
(see: docs )
