Oftentimes I like to check for a key value, and then supply a default if 
it is not there.  It can be useful to make up a routine that does this 
for you all in one step:

$rowsPerPage = arraySafe($options,'rowsperpage',25);
$orderLines = arraySafe($orders,'lines',array());

The function is:

function arraySafe($array,$key,$default='') {
  if(isset($array[$key]))
     return $array[$key];
  else
     return $default;
}
