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;
}
$p = new poo;
echo serialize($p);
----
I've tried using get_object_vars($this), and ReflectionObject($this)
both of which don't include all the properties of the instance.
the only way I can see to get all the properties of the instance is
to serialize($this) then parse the string, but that's just wrong and
what would sleep return on the first call to serialize.
any help greatly appreciated.
regards,
nathan
