[PHP] Form Posting from script

[GeneralX]

How do you post a form without actually waiting for submit button to be pressed?  Got 
a CGI expecting a form post, all the fields are already available as hidden type in a 
form, and just need to be send it.

I know you can use Java as such:

<form method="post" action="CGI.php">
<input type="hidden" name="FName" value="myFirstName">
</form>

<script type="text/javascript">
document.forms[0].submit();
</script>
