read-only properties in PHP?

Question

Is there a way to make a read-only property of an object in PHP? I have an object with a couple arrays in it. I want to access them as I normally would an array

<         


        

Answer 1

in the class, do this:

private $array;

function set_array($value) {
    $this->array = $value;
}

then you just set like this:

$obj->set_array($new_array);
