For those of a weak hart, please skip this article. Before I start presenting the idea, please note that this is just an idea. So what’s it about? In our everyday Magento development there are numerous examples/tasks where we need to import some data into Magento or programmatically create some entries like products, orders, customers, etc. When dealing with larger scale of things, importing/creating 50000 of products can turn out to be a real challenge. Usually we (the developers) strive to a simplest possible solution, which in this case ideally would be to make simple foreach loop where we would have our code handling product creation in each iteration of the loop. Technically this works, but with extreme PHP/environment configurations only.
Second thing that might come to a mind is AJAX approach, like the one seen on the default Magento store where you initiate your product import. This solution is better than previously mentioned as it eliminates the system ending up “resource-less” . If you catch my point. There is one major drawback with this approach as well. That is, this approach works only while your browser is turned on.
