Okay I'm new to the game so forgive me a small mistake but I have tested and reproduced this weird behavior for more than 6 hours.

A class wrapping multiple array variables doesn't allow to access both arrays as individual references from inside a function.

The following code does not what I expected from the language:

class test {
  VAR $firstarray;  // defining one array
  VAR $secondarray; // defining another array
	
  function testit () {
    $i = 0;
    while ($i < 14) {
      $this->$firstarray[$i] = uniqid ("test", false);
	  $this->$secondarray[$i] = uniqid ("different", false);
      echo "Set array #1, item $i to ".$this->$firstarray[$i]." and array #2 to ".$this->$secondarray[$i]."\n";
	  $i++;
	}
  }

  function doitlocal () {
    $i = 0;
    while ($i < 14) {
      $firstarray[$i] = uniqid ("test", false);
	  $secondarray[$i] = uniqid ("different", false);
      echo "Set array #1, item $i to ".$firstarray[$i]." and array #2 to ".$secondarray[$i]."\n";
	  $i++;
	}
  }
  
}

  $temp = new test;
  $temp->testit();
  echo "The (wrong) result shows that both arrays contain the same data.\n\n";
  echo "Now lets do it local:\n";
  $temp->doitlocal();
  echo "With local variables everything works as expected.";

I expected the same result from both the testit() and doitlocal() methods and that would be creating two distinctive arrays and accessing them later in the script just with different values. This seems not to be possible if the array is capsulated in the class.

I think i read the manual thorougly and haven't found a hint about this behavior :(

use $this->firstarray, not $this->$firstarray
