Hi Daniel,
I believe multipart is possible:

$postfields['salaries'] = urlencode(serialize($salaries));
$postfields['morepost'] = 'wwwwww';
$postfields['muchmorepost'] = 'zzzzwwwwww';

curl_setopt ($conn, CURLOPT_POSTFIELDS , $postfields );

makes it a multi part post. But your right, you have to build your
postfields before posting.

Example scripts:
PHPdocument1.php:
<?php
$salaries["Bob"] = 2000;
$salaries["Sally"] = 4000;
$salaries["Charlie"] = 600;
$salaries["Clare"] = 0;

$postfields['salaries'] = urlencode(serialize($salaries));
$postfields['morepost'] = 'wwwwww';
$postfields['muchmorepost'] = 'zzzzwwwwww';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://yourdomain/PHPDocument2.php' );
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields );
$response = curl_exec( $ch );
curl_close($ch);
echo $response;
?>

PHPdocument2.php
<?php
print_r($_POST);
print_r(unserialize(urldecode($_POST['salaries'])));
?>

Keep up the good work Daniel (and hopefully they once listen to you at
Zend/PHP)

Willem.

Right, but by doing the serializing stuff you also no longer make it a
multipart formpost...
