php函数echo

Question

I have:

$an = "1989";
$luna = "4";
$zi = "23";


function CalzulareZodie($date){
         list($an,$luna,$zi)=explode("-",$date);
         if(($luna==1 && $day>20)||($month==2 && $zi<20)){
              return "Varsator";
         }else if(($luna==2 && $zi>18 )||($luna==3 && $zi<21)){
              return "Pesti";
         }else if(($luna==3 && $zi>20)||($luna==4 && $zi<21)){
              return "Berbec";
         }else if(($luna==4 && $zi>20)||($luna==5 && $zi<22)){
              return "Taur";
         }else if(($luna==5 && $zi>21)||($luna==6 && $zi<22)){
              return "Gemeni";
         }else if(($luna==6 && $zi>21)||($luna==7 && $zi<24)){
              return "Rac";
         }else if(($luna==7 && $zi>23)||($luna==8 && $zi<24)){
              return "Leu";
         }else if(($luna==8 && $zi>23)||($luna==9 && $zi<24)){
              return "Fecioara";
         }else if(($luna==9 && $zi>23)||($luna==10 && $zi<24)){
              return "Balanta";
         }else if(($luna==10 && $zi>23)||($luna==11 && $zi<23)){
              return "Scorpion";
         }else if(($luna==11 && $zi>22)||($luna==12 && $zi<23)){
              return "Sagetator";
         }else if(($luna==12 && $zi>22)||($luna==1 && $zi<21)){
              return "Capricorn";
         }
    }

how can i echo the result of this function?

i've tried with:

$zodia=CalculareZodie();
echo "Zodia este: ".$zodia;  

What is wrong?

Answer 1

You need to pass the variables to the function, now, judging by the start of the function it takes a string with a date separated by dashes as an arguement so you'll need to do something like:

$an = "1989";
$luna = "4";
$zi = "23";

$date = $an . '-' . $luna . '-' . $zi;  //Construct the string from the outside variables

Then you do:

$zodia=CalzulareZodie($date); //Pass constructed string to function.
echo "Zodia este: ".$zodia;
