help doing function

[osusano]

i want to make a simple function but i cant figure it out.

<?
   $var1 = "Hello";
   $var2 = "World";

   combine($var1, $var2)
   print $wordCombined;

   function combine($var1, $var2){
      $wordCombined = $var1.' '.$var2;
      return;
   }
?>

but it dont displays the value what do u think should i do with this or maybe i code it wrong

[osusano]

what im just trying to do here is to print the combined message outside the function.. so bascially the function is used just to store the value and get it outside or return it so that i can get the value and even make some more script for that

Put the function above where you call it & print it.

Gotta return the variable...

<? 
function combine($var1, $var2){ 
    $wordCombined = $var1." ".$var2; 
    return $wordCombined;
}

$var1 = "Hello"; 
$var2 = "World"; 
$cWord = combine($var1, $var2) 
print $cWord; 
?>

...or globalize by refering.......

function combine($var1, $var2,&$foo){ 
    $foo = $var1." ".$var2;     

}
