Good PHP ORM Library?

/* SQL */
CREATE TABLE products (
    product_id INTEGER,
    description VARCHAR(128),
    PRIMARY KEY (product_id)
);

/* PHP */
// Create
$product=new Axon('products'); // automatically reads the above schema
$product->product_id=123;
$product->description='Sofa bed';
$product->save(); // ORM knows it's a new record

// Retrieve
$product->load('product_id=123');
echo $product->description;

// Update
$product->description='A better sofa bed';
$product->save(); // ORM knows it's an existing record

// Delete
$product->erase();

<?php
$object = $dorm->getClassName('id_here');
$dorm->save($object);
$dorm->delete($object);

$urun = new Product();
$urun->name=”CPU”
$urun->prince=”124”;
$urun->save();
