There is really a problem of transmitting $_POST data with curl in php 4+ at least.
I improved the encoding function by Alejandro Moreno to work properly with mulltidimensional arrays.
<?php
function data_encode($data, $keyprefix = "", $keypostfix = "") {
assert( is_array($data) );
$vars=null;
foreach($data as $key=>$value) {
if(is_array($value)) $vars .= data_encode($value, $keyprefix.$key.$keypostfix.urlencode("["), urlencode("]"));
else $vars .= $keyprefix.$key.$keypostfix."=".urlencode($value)."&";
}
return $vars;
}
curl_setopt($ch, CURLOPT_POSTFIELDS, substr(data_encode($_POST), 0, -1) );
?>
