I think its a misunderstanding on the one side and a limitation on

you can't use overloading directly on items of an overloaded array e.g:
echo $tc->arr['a']
this is triggers a call to __get() with the $key parameter set to
something like
(I'm guessing) "arr['a']"
No, I'm pretty sure (too lazy and tired right now to test...) that if
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);
'
That's weird, because I did get around to testing it before I saw your
mail, and in my test it works as *I* expect (PHP 5.1.2)...
My comments earlier were based on the fact that it would not be good to
limit what can be put in an object through __get and __set effectively
to scalar variables, and I would expect the engine developers to realise
that. I think they have (unless I've done something stupid in my test
code...):
Code:
<?php
class T {
private $array = array();
public function __get( $key ) {
return $this->array[$key];
}
public function __set( $key, $value ) {
$this->array[$key] = $value;
}
}
$t = new T;
$t->insideArray = array();
$t->insideArray['test'] = 'testing!';
var_dump( $t );
?>
Output:
object(T)#1 (1) {
["array:private"]=>
array(1) {
["insideArray"]=>
array(1) {
["test"]=>
string(8) "testing!"
}
}
}
