Question

我有一个如下数组：

$quantity = explode(",", $dataProducts["quantityArray"]);
$valuePrice = explode(",", $dataProducts["valuePriceArray"]);
$productsId = explode(",", $dataProducts["productsIdArray"]);

for($i=0;$i<count($productsId);$i++){ 

    $products = array('id' => $productsId[$i],
                      'price' => $valuePrice[$i],
                      'quantity' => $quantity[$i]);

}

假设向量由4个产品组成，它们的ID，价格和数量。（以前，我检查阵列是否已正确设防）

$ products [0] = ['id'=> 4，'价格'=> 20，'数量'=> 2]

$ products [1] = ['id'=> 10，'价格'=> 100，'数量'=> 5]

$ products [2] = ['id'=> 15，'价格'=> 40，'数量'=> 4]

$ products [3] = ['id'=> 20，'价格'=> 50，'数量'=> 3]

我将其作为参数传递给“成功”的网址。 但是当生成url时，只有数组的第一个索引到达。

$products= http_build_query($products);

#Configure the url of response for user
$preference->back_urls = array(
            "success" => "{$url}/index.php?route=profile&data=".$products,
            "failure" => "{$url}/index.php?route=error",
            "pending" => "{$url}/index.php?ruta=pending"
);

生成的url示例，仅包含数组的第一个索引：

https://www.webpage.com/index.php?route=profile&data=id=4&price=20&quantity=2

我在做什么错了？

Answer 1

为了将项目追加到数组，请使用以下语法：$array[] = $value

在您的示例中：

for($i=0; $i<count($productsId); $i++){ 
    $products[] = array(
        'id' => $productsId[$i],
        'price' => $valuePrice[$i],
        'quantity' => $quantity[$i]
    );
}

Answer 2

此：

$products[0] = ['id' => 4, 'price' => 20, 'quantity' => 2];
$products[1] = ['id' => 10, 'price' => 100, 'quantity' => 5];
$products[2] = ['id' => 15, 'price' => 40, 'quantity' => 4];
$products[3] = ['id' => 20, 'price' => 50, 'quantity' => 3];
$str = http_build_query($products);
echo $str . PHP_EOL;

生成此：

0％5Bid％5D = 4＆0％5Bprice％5D = 20＆0％5Bquantity％5D = 2＆1％5Bid％5D = 10＆1％5Bprice％5D = 100＆1％5Bquantity％5D = 5＆2％5Bid％5D = 15＆2％5Bprice％5D = 40＆2％5Bquantity％5D = 4＆3％5Bid％5D = 20＆3％5Bprice％5D = 50＆3％5Bquantity％5D = 3

如果您正在寻找这样的输出：

id=4&price=20&quantity=2&id=10&price=100&quantity=5&id=15&price=40&quantity=4&id=20&price=50&quantity=3

然后执行以下操作：

$str2 = '';

foreach($products as $product) { 
   $tmp = http_build_query($product);
   if ( ! empty($str2) ) {
      $str2 .= '&';
   }
   $str2 .= $tmp;
}
echo $str2 . "\n";

您可以将整个数组编码为JSON base 64编码。

$data = base64_encode(json_encode($products));
echo "http://example.com/?data=" . $data . PHP_EOL;

然后在接收端：

$products = json_decode(base64_decode($_GET['data']), true);

如何将数组作为url参数传递并完整接收
