[RESOLVED] find out if variable was passed to a function

[faifas]

Hello, fellow developers.

I am working on my own paginator class for a project of mine and came up with a simple issue which I am hoping to solve soon.

My question is: how do we know if variable was passed to a function when a function has a default value for that variable?

Example:

public function paginate($sQuery, $iLimit, $iPage = 1){

}

so, how do I know if I called function like this $oPaginator->paginate("SELECT ...", 20) or this $oPaginator->paginate("SELECT ...", 20, 1); ?

Thanks in advance,
Faifas

Well, the first question might be, "Does it really matter?" But assuming it does, I might set the actual default within the function.

function test($foo, $bar = null)
{
   if(!isset($bar))
   {
      $bar = 'default value';
      $suppliedByClientCode = false;
   }
   else
   {
      $suppliedbyClientCode = true;
   }
}
