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

<

If you're using PHP 5+ you can do it with __set() and __get() methods.

You have to define how they work but should do just this.

Edit an example would be like this.

class Example {
    private $var;
    public function __get($v) {
        if (is_array($v)) {
            foreach () {
                // handle it here
            }
        } else {
            return $this->$v;
        }
    }
}

This might not be the "best" way of doing it but it'll work depending on what you need
