Posting multidimensional array with PHP and CURL

Question

I\'m having trouble posting form data via CURL to a receiving PHP script located on a different host.

I get an Array to string conversion error

Answer 1

$post = "ac=on&p=1&pr[]=0&pr[]=1&a[]=3&a[]=4&pl=on&sp[]=3&ct[]=3&s=1&o=0&pp=3&sortBy=date";
parse_str($post,$fields); 

$url = 'http://example.com/';


//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);
