When a object with private variables, has converted (cast) to an array in php the array element keys will be started with

*_

. How to remove the "*_"s that exists at the beginning of array keys?

For example

class Book {
    private $_name;
    private $_price;
}

the array after casting

array('*_name' => 'abc', '*_price' => '100')

I want

array('name' => 'abc', 'price' => '100')

I did it in this way

class Book {
    private $_name;
    private $_price;

    public function toArray() {
        $vars = get_object_vars ( $this );
        $array = array ();
        foreach ( $vars as $key => $value ) {
            $array [ltrim ( $key, '_' )] = $value;
        }
        return $array;
    }
}

and when I want to convert a book object to an array I call the toArray() function

$book->toArray();
