I think I know your issue. Try adding

我想我知道你的问题。尝试添加

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

curl_setopt（$ curl，CURLOPT_RETURNTRANSFER，true）;

The PHP docs allude that if you don't do this, executing the curl will just output the contents directly to a page, which if you're using this as a script that doesn't output anything, will obviously not show anything. This should make $result equal something, and then allow you to print_r it

PHP文档提到，如果你不这样做，执行curl只会将内容直接输出到页面，如果你使用它作为不输出任何内容的脚本，显然不会显示任何内容。这应该使$ result等于某个东西，然后允许你print_r它

I would suggest you use Guzzle. It is a wrapper around CURL that abstracts away all the configuration and gives you many convenience methods for easy use.

我建议你使用Guzzle。它是CURL的一个包装器，它抽象出所有配置，并为您提供了许多便于使用的便捷方法。

You can install Guzzle by following instructions in the following link: http://guzzle.readthedocs.org/en/latest/overview.html#installation

您可以按照以下链接中的说明安装Guzzle：http：//guzzle.readthedocs.org/en/latest/overview.html#installation

Below is an example of how you could use guzzle to get what you want.

下面是一个如何使用guzzle来获得你想要的东西的例子。

    require 'vendor/autoload.php';    
    use GuzzleHttp\Client;

    $url = 'https://example.com';
    $data= array("example" => "valor");

    $client = new Client();
    $response = $client->request('PUT', $url, [
        'json' => $data
    ]);

    print_r($response);

I have used Guzzle in place of raw CURL on many projects and found it to be a great time saver.

在许多项目中我使用Guzzle代替原始CURL，并发现它可以节省大量时间。

For PUT use curl_setopt($ch, CURLOPT_PUT, true);

对于PUT，使用curl_setopt（$ ch，CURLOPT_PUT，true）;

I had the same problem. I've solved by changing

我有同样的问题。我已经通过改变解决了

curl_setopt($curl, CURLOPT_URL, $url);

至

curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");

Before, this, curl try to post a file or something similar, with 100-continue, but we need to post json.

之前，这个，curl尝试发布一个文件或类似的东西，100-continue，但我们需要发布json。
