How can data be sent from one server to another and processed by a script in PHP?

To send data from one server to another and process it with a PHP script, you can use cURL to make an HTTP request to the receiving server. The receiving server can then process the data and send a response back to the original server. The PHP script on the original server can then handle the response accordingly.

<?php
// Data to send
$data = array('key1' => 'value1', 'key2' => 'value2');

// URL of the receiving server
$url = 'http://example.com/process_data.php';

// Initialize cURL session
$ch = curl_init($url);

// Set cURL options
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Process the response
echo $response;
?>
