Stupid PHP tricks: The Array builder

class ArrayBuilder {
    public function __set($name, $value){
        return $this->$name = $value;
    }
    
    public function __call($name, $value){
        if(count($value) == 1){
            $this->$name = $value[0];
        }else{
            $this->$name = $value;
        }
        return $this;
    }
    
    public function toArray(){
        return get_object_vars($this);
    }
    
    public static function FACTORY(){
        return new ArrayBuilder();
    }

}

Usage:

  $x = ArrayBuilder::FACTORY()->hello("World")->digits(1,2,3,4,5)->foo("BaR?")->toArray();
  var_dump($x);
   array(3) {
  ["hello"]=>
  string(5) "World"
  ["digits"]=>
  array(5) {
    [0]=>
    int(1)
    [1]=>
    int(2)
    [2]=>
    int(3)
    [3]=>
    int(4)
    [4]=>
    int(5)
  }
  ["foo"]=>
  string(4) "BaR?"
}

Works great for factory scenarios and confusing the $*&! out of the unwary.
