Hi, I've done something like this: class MyClass { private $var; function __construct($value) {

    $this->var = $value;

} public function printVar() {

    echo($this->var);

} } $object = new MyClass('1'); $object->printVar(); // prints 1 $object->var = 3; // Fatal Error as expected $object->$var = 2; // no error msg

$var is empty, so this is setting a non-existent class property to 2.

$object->printVar(); // prints 2

I got 1 when running this -- just as I would expect. Are you sure it printed 2? Basically, if a property is undeclared, it is assumed public, so you can set undefined properties without issue. If defined private or protected, the calling script will not be able to alter the value.

i did write the script out of my mind, and didn't paste it. not the best idea, i know. thanks for your help, i see my mistakes very clearly. forgive a noob for such question. thanks, norbert
