Re: [PHP-DEV] Pb : access control

[Fabrice Le Coz]

here a code to test private variables
?php
// test private variables
class foo {
private $name = foo;

function __construct() {
$this-name = foo2;
}
}

class baz extends foo {
function show() {
echo  name : $this-name \n;
}
}

$test = new baz();
$test-show();
echo   name : $test-name \n;
?

this code expose the variable foo2 in the baz object (method show) which
normally can't be visible (private variable of the parent class), and expose
the variable in the main context.
Normally a fatal error must be generated when accessing private variables in
the main context (echo   name : $test-name \n;) and in the inheritance
context ($test-show();)

Hope that will help debug PHP5

 Can you cut down the script to like 10 lines and say what your result is
 and what you'd expect?

 Hi,
 
 I'm playing with PHP5 and have some trouble wtith access control, here's
the
 code I run with last php5 from snaps.php.net under windows XP :
 
 ?php
 class pere {
  private   $var3;
  public$var1;
  protected $var2;
 
  function __construct() {
  $this-var1 = public;
  $this-var2 = protected;

  function show() {
  echo pere::show() \n;
  echo var1 : $this-var1\n;
  echo var2 : $this-var2\n;
  echo var3 : $this-var3\n;
  echo \n;
  }
 }
 
 class fils extends pere {
  protected $var = fils;
  private   $var4 = test;
 
  function __construct() {
  parent::__construct();
  }
 
  function show_fils() {
  echo fils::show() \n;
  echo var1 : $this-var1\n;
  echo var2 : $this-var2\n;
  echo var3 : $this-var3\n;
  echo var  : $this-var\n;
  echo \n;
  }
 }
 
 function show_var($obj) {
  $obj_vars = get_object_vars($obj);
  foreach ($obj_vars as $name = $value) {
  if($name != ) echo $name : $value\n;
  }
  echo \n;
 }
 
 $test1 = new pere();
 $test1-show();
 echo Affichage des variables visibles de test1 :\n;
 show_var($test1);
 
 $test2 = new fils();
 $test2-show_fils();
 echo Affichage des variables visibles de test2 :\n;
 show_var($test2);
 $test2-show();
 echo var3 : .$test2-var3.\n;
 echo var4 : .$test2-var4.\n;
 ?
 
 and I've the following result :
 
 pere::show()
 var1 : public
 var2 : protected
 var3 : private
 
 Affichage des variables visibles de test1 :
 var1 : public
 
 fils::show()
 var1 : public
 var2 : protected
 var3 : private
 var  : fils
 
 Affichage des variables visibles de test2 :
 var1 : public
 var2 :
 var3 : private
 
 pere::show()
 var1 : public
 var2 : protected
 var3 : private
 
 var3 : private
 
 Fatal error: Cannot access private property fils::$var4 in
 D:\www\test\heritier.php on line 59
 
 Normally in the instance of fils object ($test2), I mustn't see
 $this-var3 which is private variable of the parent. if I comment the
line
 'echo var3 : $this-var3\n;' in the show_fils method, $test2-var3 is
 empty but do not generate an error !
 The show_var($test2) function expose a var2 variable which normally must
 send an Fatal error.

[PHP-DEV] add SMTP authentication to php.mail() function

[John M. Calvert]

Hello, I'm interested to add SMTP authentication to the php.mail() function.
Is this something that the PHP dev community would endorse? I'm told that as
a newbie contributor I wouldn't have direct access to the CVS, that I'd have
to post my diffs to this list or get an existing developer to sponsor my
changes. I already did the digging around and know what needs to happen: a
small number of lines of code in /win32/sendmail.c SendText() to add the
necessary SMTP AUTH commands. Maybe this has come up before and been
rejected. Let me know. I did a search in the list archives but didn't turn
anything up.

Here is some background:

I'm developing a website that will be hosted on a linux box (LAMP), however
my work machine is MS Windows 2000. The website includes a submission page
which e-mails some HTTP form posted data back to me. For simplicity I'm
simply using the php.mail() function. However, when I'm developing on
Windows 2000, if I want to test the mail submission, I don't have an SMTP
relay running locally and my ISP requires authentication for outgoing SMTP.
So for now the php.mail() fails and I fake it until the php pages are
uploaded to the server. I know I could switch to another means of sending
mail (PHP class for SMTP, etc) but I thought it would be cool to hack PHP to
add this minor feature. I would plan to add two new php.ini settings
SMTP_usr and SMTP_pwd.

Looking forward to your comments.
