functions

[alund1987]

This might be a really stupid question but if I have a function with two inparameters do I have to return them both, by the way I am going to use just one of the inparameters..as the example shown below:

function check($array1, $array2) {
for($i =0; $i <=10; $i++) {
  if($array2 ==1) {
  $array[$i] = rand(1, 5);
}
  }
return($array1);
}

Is this ok?

You can return whatever you want. You do not have to return one of the inputs, in fact doing so is kind of useless.
