如何將數組添加到URL或發送數組？

Question

好吧，我有一個捲曲請求，我正在努力。

$ch = curl_init(); 
// set URL and other appropriate options 
curl_setopt($ch, CURLOPT_URL, "http://someurl.com/shop_pos/index.php?route=module/cart/ajax_get_all_products"); 

// Do a POST 
$items = 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $_SESSION['cart']); 
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_VERBOSE, true); 
$result = curl_exec($ch); 
curl_close($ch); 
echo $result; 

內容或$_SESSION['cart']是

Array 
(
    [155] => 1 
    [78] => 1 
) 

我需要發送這個數據無論是作爲發佈數據或在捕捉功能得到變量...任何建議

public function ajax_get_all_products(){ 
    $this->language->load('module/cart'); 
    $all_products = $this->cart->getProducts(); 
    $data_returned = json_encode($all_products); 
    echo "<pre>".print_r($_REQUEST, true)."</pre>"; 
    echo "<pre>".print_r($_POST, true)."</pre>"; 
    $this->response->setOutput($data_returned, $this->config->get('config_compression')); 
} 

我沒有得到我設置的數組。這兩個文件是在同一臺服務器上BTW

Answer 1

嘗試：

curl_setopt($ch, CURLOPT_POSTFIELDS, array('items' => $_SESSION['cart'])); 

試試這個：

$post_data = http_build_query(array('items' => $_SESSION['cart'])); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); 

Answer 2

試試這個

$post = ""; 
    $amp = ""; 
    foreach($_SESSION['cart'] as $key => $value) { 
     $post .= $amp . $key . "=" . urlencode($value); 
     $amp = "&";       
    } 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);

嘗試使用PHP的序列化和反序列化功能
