)

Key as SKU and Value as Quantity means [sku] => quantity so how to change quantity

Answer 1

The load method accepts the field to load on as a second argument. In this case that would be sku

$productId = Mage::getModel('catalog/product')->getIdBySku([the SKU], 'sku');
$product = Mage::getModel('catalog/product')->load($productId);

$stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product);
// some default stock settings that you might need
$stockItem->setData('manage_stock', 1);
$stockItem->setData('is_in_stock', 1);
$stockItem->setData('use_config_notify_stock_qty', 0);

$stockItem->setData('qty', [the quantity]);

$stockItem->save();
