Sending data to third-party server then retrieving data back
<p>Is this possible within PHP:</p>

<ol>
<li>User fills in form on my site</li>
<li>The form submits the data from the form to a third-party server somewhere else on the net, essentially handing off the data to the third-party server somehow</li>
<li>Said third-party server does something with the data and then generates a numerical value to send back to my PHP script</li>
<li>My server/PHP script gets that numerical value/data for use in the script again</li>
</ol>

<p>Is it doable in PHP? Does PHP have inbuilt functions to perform the above tasks? Would such a thing require tons of advanced code or is it relatively easy to do?</p>

<p>Thanks in advance for any help on the matter</p>
