[PHP] Passing objects as a reference and extracting the index of an associative array.

[Webmaster]

Hi,

i am using the smarty template engine.
Here is the problem that I would like to ask about:

function initTop(&$page, $array)
{
  for ($i=0; $i<sizeof($array)
  {
      $page->assignVars(, $array[$i])
  }
}


The function is supposed to know which object's attributes she is supposed
to change. Do I have to pass the object as a reference? Have never worked
with References before.

The array is supposed to be associative.
The funcion assignVars() is called like this:

$objektname->assignVars("indexname of ass. array", $arraywert);

How do I get the indexname for each arrrayvalue, so I can pass it to the
function assignVars?

Is there a php function?

Thank you very much.
