Curl doesn't update database - php

Question

I am trying to update my online database with the offline version. The following code executes without giving an error code but the expected result is not showing. Any help will be really appreciated as series of Google searching proved abortive.
<?php
include("inc_files/inventory.php");
// update sales_rec records
$get_sales_rec = mysql_query("SELECT * FROM sales_rec WHERE status = '0' ORDER BY id ASC") or die(mysql_error());
while($rec = mysql_fetch_array($get_sales_rec)){
$id = $rec['id'];
$receipt = $rec['receipt'];
$customer = $rec['customer'];
$total = $rec['total'];
$amount = $rec['amount'];
$balance = $rec['balance'];
$discount = $rec['discount'];
$date = $rec['date'];
$time = $rec['time'];
? $type = "sales_rec";
$ch = curl_init(); // initiate curl
$url = "http://www.sample.com/inventory/test.php"; // where you want to post data
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true); // tell curl you want to post something
curl_setopt($ch, CURLOPT_POSTFIELDS, "type=$type&r=$receipt&c=$customer&t=$total&a=$amount&b=$balance&d=$discount&dt=$date&ti=$time"); // define what you want to post
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return the output in string format
$output = curl_exec ($ch); // execute
curl_close ($ch); // close curl handle
}
?>

Answer 1

have you tried passing an array
$data = array('name' => 'aaa', 'title' => 'dev');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
