The steps for programmatically creating a node are:
- Create a PHP object representing the node data
- Save the object using the node_save() function
While the mechanics are simple, there is an important responsibility involved. The Drupal work flow does data validation before calling the node_save() function; node_save() does no validation. By calling node_save() directly your code takes the responsibility for providing valid data.
Drupal 7 Changes

Body Field Is No Longer Special
In Drupal 6 the body field was special. Specifically, it had a different data structure than other fields and it always existed, even if it wasn't used. With Drupal 7 the body field is a standard field provided by core and is truly optional.
Language
Language specification is required for the node and some fields.

The following code assumes an unchanged Drupal 7 Standard installation and will create a Drupal 7 article node.
