[PHP-DEV] need inverted __sleep?

Hi All,

hoping somebody can help me here..

I need to implement an inverted __sleep method, by which I mean to 
specify what variables should not be included.

use case:
<?php
class base
{
   private $notToBeSerialized;

   public function __sleep()
   {
     // TODO code return instance properties excluding $notToBeSerialized
   }

}

class foo extends base
{
   private $bar;
}

class poo extends foo
{
   private $baz;
}

get_class_vars + array_diff

cheers but nope; as the manual says
"Returns an associative array of default public properties of the class"

need private and inherited private

Re: [PHP-DEV] need inverted __sleep?

matt.. that's public properties on a single class - see the usecase

use case:
<?php
class base
{
   private $notToBeSerialized;

   public function __sleep()
   {
     // TODO code return instance properties excluding $notToBeSerialized
   }

}

class foo extends base
{
   private $bar;
}

class poo extends foo
{
   private $baz;
}

$p = new poo;
echo serialize($p);

Re: [PHP-DEV] need inverted __sleep?

Hi,

Matt's approach works also for your usecase, casting to array returns
all the properties of the class and base classes, but it has some
problems: for private properties the class name is added before the
property name, and for protected properties * is added, both things
added are between null characters, so you can remove the added string
with some regexp.

Another approach that will work is using ReflectionClass and the
method getProperties, it will return all the properties (even
private), but only of the class itself, it won't return the properties
declared in base classes, you have the get the base class
(get_parent_class) and recursively do the same thing for all the base
classes.

Regards,
Jonathan

doh, thanks Jonathan and thanks Matt - completely missed that (array) 
even though I'd been using it in a different attempt using Serializable

small note is that you do not need to remove the class names or 
suchlike, this works fine (and I assume is faster than recursive reflection)

public function __sleep()
{
   $exclude = chr(0) . __CLASS__ . chr(0) . 'notToBeSerialized';
   return array_diff(array_keys((array)$this) , array($exclude) );

I've recently fixed the manual about get_class_vars, since PHP 5.0.5
get_class_vars, depending on the scope will return the properties
thats accessable from this scope, so calling it inside a method will
expose both its public/protected/private properties.
