Hi internals,
casting an object to array gives the possibility to get the values of protected/private
member variables :
<?php
class some {
public $pub = 1;
protected $prot = 2;
private $priv = 3;
}
var_dump((array)new some());
?>
Produces :
array(3) {
["pub"]=>
int(1)
["*prot"]=>
int(2)
["somepriv"]=>
int(3)
}
IMO, when casting to array with (array) only the public-ly visible members should returned.

Dunno, E_STRICT (as you can access them without notice/warning without
this flag)?
In the same manner:
<?php
error_reporting(E_STRICT);
class some {
public $pub = 1;
protected $prot = 2;
private $priv = 3;
}
class any extends some {
public $pub1 = 1;
function dump() {
var_dump($this);
}
}
var_dump((array)new any());
$a = new any;
$a->dump();
?>
a var_dump should dump protected props from the parent class as they are
visible. Note the "funny" thing is that var_dump() alone do not display
the public|protected props, whatever is the context call. IMHO, that
sounds not very consistent, but only imho...

Yes, it does not. Useprint_r()for dumping.print_r()uses internal zend function to dump
the variable content whilevar_dump()is defined in ext/standard/var.c and knows nothing
about protected and private functions (or at least it was that 2 months ago).
print_r()has the expected behavior of dumping data, but casting to array and getting
protected/private data is nasty.

Public/protected/private is there to protect you from bugs due to name
clashes when you extend classes. It is not a sandbox to protect you from
'malicous' programmers.
And I like it that way: PINJ(Y) - PHP is not Java (yet)
Even though some people push it that way ;-)
