How to integrate parser onto Word Press website?

I have created a PHP parser, that copies data from other websites.
How to organically integrate it into word press website? How to make the very same parser post them into the ‘Posts’ section of word press?

There are many solutions for this:

  1. Use wordpress API
    2. Import to the DB
    3. create cron schedule

It depends from what exactly you need this for, and how you are going to use this in the future.
