用PHP为CURL Post构建一个数组

Question

如何在php中为curl post构建一个数组而不覆盖上一个字段？标题在帖子中显示了以下内容：

Content-Disposition: form-data; name="price[][unit]"
One
-----------------------------122371200014463
Content-Disposition: form-data; name="price[][price]"
50
-----------------------------122371200014463
Content-Disposition: form-data; name="price[][unit]"
Two
-----------------------------122371200014463
Content-Disposition: form-data; name="price[][price]"
95
-----------------------------122371200014463
Content-Disposition: form-data; name="price[][unit]"
Three
-----------------------------122371200014463
Content-Disposition: form-data; name="price[][price]"
140

当我试图构建这样的数组时，我一直覆盖前面的项目：

$postPrice['price[][unit]']   =  'One';
$postPrice['price[][price]']   =  $one;
$postPrice['price[][unit]']   =  'Two';
$postPrice['price[][price]']   =  $two;
$postPrice['price[][unit]']   =  'Three';
$postPrice['price[][price]']   =  $three;

您可以尝试：

$fields = array(
            'price[][unit]' => "One",
            'price[][price]' => $one
            )
        );
$fields_string = http_build_query($fields);

然后：

curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
