MAGENTO 1.X – REMOVE ITEMS FROM A COLLECTION WHEN ITERATING

Sometimes you may need to remove items from a collection (eg: products) after it was loaded, or when you are iterating it.

The following example shows you how can you remove non enabled products items from a product collection. The respective collection have to be inherited from Varien_Data_Collection.

$products = Mage::getModel('catalog/product')->getCollection()

->addAttributeToSelect("*")

->load();

foreach ($products as $_product) {

if($_product->getStatus() != Mage_Catalog_Model_Product_Status::STATUS_ENABLED){

$products->removeItemByKey($_product->getId());

}
