Can you post data from PHP
<p>I need to cause a user's browser to post data using PHP to another site.</p>

<p><strong>Example:</strong> You go to start.com/auto-login-hack (via GET)... then PHP sets the right headers etc. and causes the browser to, via POST, go to 3rdparty.com/login.php with login credentials.</p>

<p>I have done this is the past by having an HTML form and an <code>onload</code> script that submits the form to the destination.</p>

<p>I don't know enough about headers and etc. Is this possible? Can anyone link an example? My search skills just turned up how to use <code>$_POST</code>.</p>

<p>Thanks.</p>
