<?php 

/** 
 * Send a POST requst using cURL 
 * @param string $url to request 
 * @param array $post values to send 
 * @param array $options for cURL 
 * @return string 
 */ 
function curl_post($url, array $post = NULL, array $options = array()) 
{ 
    $defaults = array( 
        CURLOPT_POST => 1, 
        CURLOPT_HEADER => 0, 
        CURLOPT_URL => $url, 
        CURLOPT_FRESH_CONNECT => 1, 
        CURLOPT_RETURNTRANSFER => 1, 
        CURLOPT_FORBID_REUSE => 1, 
        CURLOPT_TIMEOUT => 4, 
        CURLOPT_POSTFIELDS => http_build_query($post) 
    ); 

    $ch = curl_init(); 
    curl_setopt_array($ch, ($options + $defaults)); 
    if( ! $result = curl_exec($ch)) 
    { 
        trigger_error(curl_error($ch)); 
    } 
    curl_close($ch); 
    return $result; 
}

So how do I go sending multiple invoice in HTTP post something like this

{
"funcrr":"create_insert_new_delivery",
"data":{
"name":"James",
"email":"james@someone.com",

//MORE OF LIKE AN ARRAY BUT IN HTTP FORM
"product_name":"Pear",
"product_weight":"30",
"product_name":"Rice",
"product_weight":"60",
"product_name":"Yoghury",
"product_weight":"100",
.................................................
"product_name":" n..,
"product_weight":" n,
}
}
