RE: Storing inheritance info in a DB

Hi All, 
I've tested Shandy's code; this seems to work as expected (I've stripped 
db-related functions for simplicity).

<?
class Fruit
{
    var $weight;

    function recThaw( $id )
    {
        $fruitType = "Banana"; // This value should come from a DB

        $str = "\$temp = new $fruitType;";
        eval( $str );
  
        $temp->thaw($id);
	$temp->weight = 3; // This value should come from a DB
    
        //$this = $temp; <-- Win95+Apache+PHP crashes here :-(
	return $temp;
    }

    function whatami() { echo "<BR>Fruit"; }
}

class Banana extends Fruit
{
    var $length;

    function thaw( $parentID )
    {
		$this->length = 5; // This value should come from a DB
    }

    function whatami() { echo "<BR>Banana"; }
}


$asdf = new Fruit;
$asdf = $asdf->recThaw(1);
$asdf -> whatami();
echo "<BR> asdf-weight: ". $asdf->weight;
echo "<BR> asdf-length: ". $asdf->length;
?>


Hope this help!
Lou
