Magento如何克隆自定义集合

Question

I need to clone my custom collection.

When I'm using the clone it makes it as reference.

In the example below the $myCollection will have the same Select as the cloned on:

$cloneCollection = clone $myCollection;
$cloneCollection->addFieldToFilter('my_field', 'my_value');

PS. I saw that you can clone some core collections this way, but it wont work for the custom collections for some reason.

Thanks.

try this

$cloneCollection = clone $myCollection;
$cloneCollection->clear();
$cloneCollection->addFieldToFilter('my_field', 'my_value');

hope this help you
