Re: [PHP] Function definition: how to make default argument an empty array?

[Bogdan Stancescu]

Can't test it now, but have you tried

function makeyogurt ($flavour, $type = list())

I assume you need it to be an array because you want to either walk it or, more
likely, perform an in_array() test on it and you found that passing non-array
variables to in_array issues an error. If initializing as an array doesn't work
you can always do this:

function makeyogurt ($flavour, $type = "") {
  while ((is_array($type)) && (list($key,$val)=each($type)))
  {
    [loop]
  }
}

or this:

function makeyogurt ($flavour, $type = "") {
  if ((is_array($type)) && (in_array("strawberry_yoghurt",$type)))
  {
    [loop]
  }
}

or use the stone-age method:

function makeyogurt ($flavour, $type = "") {
  if (@in_array("strawberry_yoghurt",$type))
  {
    [loop]
  }
}
