[PHP] returning early from a function.

[Chris W]

I have a function that does several tests and if any are true it needs 
to return false but I get an error about unexpected return for all 
returns except for the last one.

function test($s)
{
  if($s = 'this') return false;
  if($s = 'that') return false;
  return true;
}
any ideas on how to make this work or why it doesn't work?
