Question

Is it possible for PHP to log into websites and interact with them?

If so, what technologies do I need to start looking into?

Basically, what I need to do is fill out forms using PHP. I suppose cURL could do this, but I’m not entirely sure.

Answer 1

Your question is very broad, but basically:

1. Use cURL to get the HTML of a page.
2. Parse the HTML and find form elements (see this answer on HTML parsing).
3. Generate data to submit based on the inputs in the form.
4. Use cURL to create a request to the submit attribute of the form (making sure to use the specified method).
