public $id;

public function ToSynchData(){
    $this->id = 1;
}

$new = new User;
$new->ToSynchData();
echo $new->id; // 1

EDIT: Why static all of a sudden?

What da! Men it works! But I really wonder I tried that a couple of times but it doesn't work. thanks – Robin Carlo Catacutan Jul 26 '12 at 08:53
Please accept if it works. :) (Click the V under the down arrow) – Sherlock Jul 26 '12 at 08:59
Oh and by the way, your problem was the way you referred to the variables. It's $this->var, not $this->$var. – Sherlock Jul 26 '12 at 08:59
see the access modifier. it `public` only whereas OP has `static public` – xkeshav Jul 26 '12 at 09:00
It *was* just public, he modified his post. – Sherlock Jul 26 '12 at 09:00

class User{
    public $id;
    public function ToSynchData(){
        $this->id = "1";
    }
}

$new = new User();
$new->ToSynchData();
print_r($new->id);

you are trying to access static property with -> whereas it is clearly written here

Static properties cannot be accessed through the object using the arrow operator ->.

therefore to access it you have to change it from static public to public
