[PHP-DEV] Unset semantic on instance var

[Mathieu Suen]

Hi,

try:
_______
class A
{
   protected $a;
   public function __construct()
   {
       if(!isset($this->a))
       {
           $this->a = 'd';
           echo '1st';
       }
       unset($this->a);
       if(!isset($this->a))
       {
           $this->a = 'g';
           echo '2nd';
       }
   }
    public function __set($columnName, $value)
    {
        echo 'New value : ' . $value . ' for '. $columnName;
    }
}

new A();
______

unset mean removing the instance variable from the class!!

I was using the lazy initialisation with the isset function but then 
now I will initalize all inst var with null and check with the is_null 
function.

Would it be possible to have inst var null by default insthead of a 
pseudo unset/null variable.
Thanks

Cheers
