Re: Overloading Limitation- Can Someone Confirm?

could you both take a look at this (I posted it already btw) - notice that the second 'set' action ($t->insideArray["test"] = "testing!";) is not going via __set() at all, it uses __get() BUT/AND then an item is set in the returned array ... and also in the [sub] array stored inside the object (even though nothing is being returned by reference): (I feel that this is not right somehow!) <?php class T {

    private $array = array();

    public function __get( $key ) {
    echo "Getting $key\n";
        return $this->array[$key];
    }

    public function __set( $key, $value ) {
    echo "Setting $key\n";
        $this->array[$key] = $value;
    }

} $t = new T; $t->insideArray = array(); $t->insideArray["test"] = "testing!"; var_dump( $t ); ?> OUTPUT: Setting insideArray Getting insideArray object(T)#1 (1) { ["array:private"]=> array(1) {

    ["insideArray"]=>
    array(1) {
      ["test"]=>
      string(8) "testing!"
    }

you guess wrong :-) .. I couldn't resist testing it: php -r ' class T { private $var = array(); function __set($k, $v) { $this->var[$k] = $v; }

function __get($k)     { var_dump($k); }

} $t = new T; $t->arr = array(); $t->arr["a"] = 1; echo "OUTPUT: \n"; var_dump($t->arr); var_dump($t->arr["a"]); var_dump($t); '

Code: <?php class T {

    private $array = array();

    public function __get( $key ) {
        return $this->array[$key];

    public function __set( $key, $value ) {

Dont know if you guys see the MAJOR difference between your code, so I will point it out. Jasper did this

function __get($k)     {

var_dump($k); }

Uhm, no I didn't. Jochem did :)

Jochem did this public function __get( $key ) { return $this->array[$key]; }

No, I did that.

First off, the required public before the function call was not included, secondly, Jasper is var_dumping the key of the array, not the array it self.

Public is not required. I always put it regardless, but if you leave it off then PHP defaults to public for compatibility reasons. Jochem's code, which behaves incorrectly, does var_dump. Mine just returns the array key as you would expect. That's why Jochem's doesn't behave correctly with arrays.
