Hi

The __set() magic function is called whenever an undefined class
variable is set

<?
class Foo
{
public function __set($sProp, $Val)
{
if(in_array($sProp, $this->arrProps)){
echo "Found Class Property '$sProp'<br>";
}
else{
echo "Invalid Prop '$sProp'<br>";
$this->{$sProp} = $Val; // define it ;)
}
}

protected $arrProps = array("FirstName", "LastName");

public $Test = "";
}

$Foo = new Foo();
$Foo->FirstName = "Hugo";

// __set gets called
$Foo->tName = "Hugo";

// tName is defined
echo $Foo->tName;

// no __set gets called
$Foo->tName = "Hugo3";

echo $Foo->tName;

// no __set gets called because of object member
$Foo->Test= "no set calles";
?>

hope this helps
