Clear all object variables

[Bengaltgrs]

I have a class and I would like to create a function to clear all variables within the object, regardless of how many variables are added or taken out. Something like this..

class object()
{
$a;
$b;
$c;

function clear_data()
{
foreach(variable in this object)
variable = null;
}
}

Is there a built in PHP function to handle this?

foreach($object as $property => $value)  {  
    unset($object->$propery);  
} 

... though surely it would be easier to just create a new object?

Don't think that was quite what I was looking for. The reason I was looking for a way to clear all variables in an object is this. The object has a function called load, that just loads a bunch of data from the DB. If while loading, it finds a bad piece of data, I want it to clear all the variables within the object.

I could make a function called clear() and just have it do something like:

$this->a = null;
$this->b = null;
$this->c = null;

The problem is, I want this class to be inherited, so that any child class can use this method and it will work.

Something like this?

<?php
class Foo
{
   public $a;
   public $b;
   public function clearAllVars()
   {
      $vars = get_object_vars($this);
      foreach($vars as $key => $val)
      {
         $this->$key = null;
      }
   }
}

// TEST:
?>
<pre><?php
$foo = new Foo();
$foo->a = 'a';
$foo->b = 'b';
$foo->c = 'c'; // create new object variable
var_dump($foo);
$foo->clearAllVars();
var_dump($foo);
?></pre>

Output:

object(Foo)#1 (3) {
  ["a"]=>
  string(1) "a"
  ["b"]=>
  string(1) "b"
  ["c"]=>
  string(1) "c"
}
object(Foo)#1 (3) {
  ["a"]=>
  NULL
  ["b"]=>
  NULL
  ["c"]=>
  NULL
}

Ah, perfect. Thank you very much.
