What is CURL? Is it a function, script, API or what?

By using this function you can send a post request with an optional number of
parameters. Just fill in the postdata array with key values pairs.
Example usage are provided.
通过使用此函数，您可以发送带有可选参数数量的 post 请求。只需用键值对填充 postdata 数组。提供了示例用法。
<?php
function do_post_request($url, $postdata)
{
$content = "";
// Add post data to request.
foreach($postdata as $key => $value)
{
$content .= "{$key}={$value}&";
}
$params = array('http' => array(
'method' => 'POST',
'header' => 'Content-Type: application/x-www-form-urlencoded',
'content' => $content
));
$ctx = stream_context_create($params);
$fp = fopen($url, 'rb', false, $ctx);
if (!$fp) {
throw new Exception("Connection problem, {$php_errormsg}");
}
$response = @stream_get_contents($fp);
if ($response === false) {
throw new Exception("Response error, {$php_errormsg}");
}
return $response;
}
// Post variables.
$postdata = array(
'username' => 'value1',
'password' => 'value2',
'param3' => 'value3'
);
do_post_request("http://www.example.com", $postdata);
?>

cURL is a library "that allows you to connect and communicate to many different types of servers with many different types of protocols". So you can use cURL to send an HTTP POST request. Please read the PHP manual for detailed information: http://www.php.net/manual/en/book.curl.php
cURL 是一个库，“它允许您使用许多不同类型的协议连接和通信到许多不同类型的服务器”。因此，您可以使用 cURL 发送 HTTP POST 请求。详细信息请阅读PHP手册：http: //www.php.net/manual/en/book.curl.php
But cURL is not the only answer. You can use PHP Streams, or even connect to the webserver using socket functions and then generate your requests.
但是 cURL 并不是唯一的答案。您可以使用PHP Streams，甚至可以使用套接字函数连接到网络服务器，然后生成您的请求。
Personally I often use cURL because it's very flexible and you can work with cookies easily.
就我个人而言，我经常使用 cURL，因为它非常灵活，您可以轻松使用 cookie。

Simply use: file_get_contents()
只需使用： file_get_contents()
// building array of variables
$content = http_build_query(array(
'username' => 'value',
'password' => 'value'
));
// creating the context change POST to GET if that is relevant
$context = stream_context_create(array(
'http' => array(
'method' => 'POST',
'content' => $content, )));
$result = file_get_contents('http://www.example.com', null, $context);
//dumping the reuslt
var_dump($result);
