Description:
------------
In a class I send an array $test as a parameter to a protected function. Then, if I try to access that array in any way in that function, suddenly the $this object contains the data of that array $test (!)

Reproduce code:
---------------
Sorry, cant make a short-and-clear reproducing code, but here I have a small code sample that actually caused the problem: (note that $this->params["source"] _IS_ an array)

protected function get_body($css){

echo "B0 (";
print_r($this);
echo ")<br>";
flush();

  $retval="";
  while(list($key, $cell_data)=each($this->params["source"])){

  echo "B1 (";
  print_r($this);
  echo ")<br>";
  flush();



Expected result:
----------------
I will try to get a .zip together with the classes that seem to cause this problem.

Actual result:
--------------
B0 (table_key_value_a Object ( [params:protected] => Array ( [source] => Array ( [crc] => mBjsS50UkhAnxjWp [sid] => 75 [test_site] => 75,mBjsS50UkhAnxjWp ) [col headers] => Array ( [0] => Key [1] => Value ) [table header] => HTTP VARIABLES [css prefix] => debug [table header extra] => align='center' ) ) )

B1 (table_key_value_a Object ( [cell_data] => mBjsS50UkhAnxjWp [key] => crc ) )
