How do I have to add a collection of products in Magento?

[jordano]

I need to add about 100.000 records in my Magento Store. I have already the function that helps me to add a product but I need to improve it using the collections of products.This is my custom function:\[code\]public function Products($data){ try{ foreach($data as $record){ $product = Mage::getSingleton('catalog/product'); $productId = $product->getIdBySku($record[3]); if($productId){ $product->load($productId); } // Build the product $product->setManufacturer($this->addManufacturers(utf8_encode($record[4]))); $product->setSku($record[3]); $product->setAttributeSetId($this->attribute_set);# 9 is for default $product->setTypeId('simple'); $product->setName(utf8_encode($record[5])); $product->setCategoryIds(array(1,2,3)); # some cat id's, $product->setWebsiteIDs(array(1)); # Website id, 1 is default $product->setDescription(utf8_encode($record[6])); $product->setShortDescription($this->shortText(utf8_encode($record[6]), 150)); $product->setPrice($record[9]); # Set some price //Default Magento attribute $product->setWeight($record[12]); $product->setStatus( Mage_Catalog_Model_Product_Status::STATUS_ENABLED ); $product->setVisibility(Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH); $product->setTaxClassId(0); # default tax class // Manage stock $product->setStockData(array( 'is_in_stock' => Mage_CatalogInventory_Model_Stock::STOCK_IN_STOCK, // ou Mage_CatalogInventory_Model_Stock::STOCK_OUT_OF_STOCK 'qty' => 1000, )); $product->setCreatedAt(strtotime('now')); $product->setIsMassupdate(true); $product->setExcludeUrlRewrite(true); $product->save(); $ID = is_numeric($productID) ? $productID : $product->getId(); unset($product); unset($productId); } }catch(Exception $e){ die($e->getMessage()); }}\[/code\]How do I have to change this function using the collection?Thanks
