Problem POSTing an multidimensional array using cURL PHP

I'm having problems posting an array using PHP cURL. I have successfully posted other values to the same page using POST-variables. But this one is hard to figure out. The only problem is how I should present the data to the server.

I checked the original form using a form analyzer. And the form analyzer shows that the POST variables are sent like this:

array fundDistribution' => 
     array
        204891 => '20' (length=2)
        354290 => '20' (length=2)
        776401 => '20' (length=2)
        834788 => '40' (length=2)

The values are just for showing an example. But they will be the same length.

My problem is that the responding server does开发者_JAVA技巧 not recognise the values when I send them like this:

Array(
[104786] => 20
[354290] => 20
[865063] => 20
[204891] => 20
[834788] => 20)

My question is: How do I send the data so the server understands it?

Thank you!

function flatten_GP_array(array $var,$prefix = false){
        $return = array();
        foreach($var as $idx => $value){
                if(is_scalar($value)){
                        if($prefix){
                                $return[$prefix.'['.$idx.']'] = $value;
                        } else {
                                $return[$idx] = $value;
                        }
                } else {
                        $return = array_merge($return,flatten_GP_array($value,$prefix ? $prefix.'['.$idx.']' : $idx));
                }
        }
        return $return;
}
//...
curl_setopt($ch, CURLOPT_POSTFIELDS,flatten_GP_array($array));

As the Sepehr Lajevardi says, You should use:

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($your_array));

You need to set post to true. Then you can pass the associative array in the POSTFIELDS option. as shown below.

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $your_array);

Try this:

function postVars($vars,$sep='&') {
    $str = '';
    foreach( $vars as $k => $v) {
        if(is_array($v)) {
            foreach($v as $vk=>$vi) {
                $str .= urlencode($k).'['.$vk.']'.'='.urlencode($vi).$sep;
            }
        } else {
            $str .= urlencode($k).'='.urlencode($v).$sep;
        }
    }
    return substr($str, 0, -1);
}
