title: How to send HTTPS posts using php
body: <p>I'm setting up a custom e-commerce solution, and the payment system I'm using requires me to send HTTPS POSTS.</p>
  
  <p>How can I do this using php (and CURL?), is it any different from sending http posts?</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>Thanks for your replies, they've been very useful. I assume I will need to purchase an SSL certificate for this to work, and I will obviously do this for the final site, but is there any way for me to test this without buying one?</p>
  
  <p>Thanks, Nico</p>
