Subject: __set() / __get() : limitation and/or unintentional behavoiur?
From: jochem@iamjochem.com (Jochem Maas)

I ran the following code on 5.0.4 and 5.1.0 with identical results...

Could someone shed light one whether the observed behaviour is
intentional and/or correct?

I expected that one of the following would occur (which obviously doesn't :-):

1. the line commented with 'SET 2' would trigger a
call to __set() (which should fail?).

2. the key "test" would be set in the array returned
by __get() but not it the relevant array stored in
$this->array["insideArray"].

The reason I question whether what si observed below is wanted behaviour is
because I thought the __set() functionality was there to be able
to protect/control what stuffed into an object ... but apparently it's
rather easy to side step.

tia,
Jochem

<?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(); 		// SET 1
$t->insideArray["test"] = "testing!";   // SET 2

var_dump( $t );

?>

OUTPUT:

Setting insideArray
Getting insideArray
object(T)#1 (1) {
   ["array:private"]=>
   array(1) {
     ["insideArray"]=>
     array(1) {
       ["test"]=>
       string(8) "testing!"
     }
   }
