我有一个通过 POST 提交的表单，一旦提交表单，我就会捕获变量。

如何连接表单数据，然后将其发布到 url，然后重定向到感谢页面？

这不是确切的代码，我只是找不到任何正常的答案，而且我确信有不止一种方法可以做到这一点。只是想找出最简单的方法。

if(isset($_POST['submit'])){
    $var1 = $_POST['var1'];
    $var2 = $_POST['var2'];

$url = 'https://api.this.com/foo/bar?token=IHAVETOKEN&foo=$Var1&bar=$var2'

post_request_to($url);

header("Location: thankyou.php");
}

编辑:

这是实际答案/工作代码:

if(isset($_GET['submit'])){
  $firstName = $_GET['firstname'];
  $lastName = $_GET['lastname'];
  $email = $_GET['email'];
  $password = $_GET['password'];
  $phone = $_GET['phone'];
}

  $data = array(
        'token' => 'sadfhjka;sdfhj;asdfjh;hadfshj',
        'firstName' => $firstName,
        'lastName' => $lastName,
        'email' => $email,
        'password' => $password,
        'phone' => $phone

    );


  $postvars = http_build_query($data) . "\n";

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'https://api.com/foo/bar?');
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

  $server_output = curl_exec ($ch);

  curl_close ($ch);

http_build_query

(PHP 5, PHP 7) http_build_query — Generate URL-encoded query string

例子:

<?php
$data = array(
    'foo' => 'bar',
    'baz' => 'boom',
    'cow' => 'milk',
    'php' => 'hypertext processor'
);

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&amp;');

?>

上面的例子将输出:

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor

其余的取决于您的流程逻辑。要发布到另一个脚本:

从这里 answer :

Possibly the easiest way to make PHP perform a POST request is to use cURL, either as an extension or simply shelling out to another process. Here's a post sample:

// where are we posting to?
$url = 'http://foo.com/script.php';

    // what post fields?
    $fields = array(
       'field1' => $field1,
       'field2' => $field2,
    );

    // build the urlencoded data
    $postvars = http_build_query($fields);

    // 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, $postvars);

    // execute post
    $result = curl_exec($ch);

    // close connection
    curl_close($ch)
