HTML/PHP Post method to different server
提问by rom
I want to create a POST method form that sends details to a PHP script on another server (ie, not its localhost). Is this even possible? I imagine GET is fine, so is POST possible?
我想创建一个 POST 方法表单，将详细信息发送到另一台服务器（即，不是其本地主机）上的 PHP 脚本。这甚至可能吗？我想 GET 很好，那么 POST 可能吗？

<form method="POST" action="http://the.other.server.com/script.php">

If you want to do that on your server (i.e. you want your server to act as a proxy) you can use cURL for that.
如果您想在您的服务器上执行此操作（即您希望您的服务器充当代理），您可以使用 cURL。
//extract data from the post
extract($_POST);
//set POST variables
$url = 'http://domain.com/get-post.php';
$fields_string = "";
$fields = array(
'lname'=>urlencode($last_name), // Assuming there was something like $_POST[last_name]
'fname'=>urlencode($first_name)
);
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
$fields_string = rtrim($fields_string,'&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
However if you just simply want to send a POST request to another server, you can just change the actionattribute:
但是，如果您只是想将 POST 请求发送到另一台服务器，则只需更改action属性：
<form action="http://some-other-server.com" method="POST">

There is another question on Stack Overflow that shows a better way to url-ify the variables. It is better because the method shown in the answer above breaks when you use nested associative arrays (aka hashes).
Stack Overflow 上还有另一个问题，它展示了一种更好的方法来对变量进行 url 化。更好，因为当您使用嵌套关联数组（又名哈希）时，上面答案中显示的方法会中断。
How do I use arrays in cURL POST requests
If you are really wanting to build that query string manually, you can. However, http_build_query will make your "url-ify the data for the POST" section unnecessary. – Benjamin Powers Nov 28 '12 at 2:48
如果您真的想手动构建该查询字符串，则可以。但是，http_build_query 将使您的“对 POST 的数据进行 url-ify”部分变得不必要。– 本杰明·鲍尔斯 2012 年 11 月 28 日 2:48
