What are the best practices for passing and receiving data between PHP scripts using HTTP methods?

When passing and receiving data between PHP scripts using HTTP methods, it is important to use secure methods such as POST requests to send sensitive data and GET requests for non-sensitive data. To pass data between scripts, you can use the $_POST or $_GET superglobals to retrieve data from forms or URLs. It is also recommended to validate and sanitize the data received to prevent security vulnerabilities. 

// Sending data from one PHP script to another using POST method
$data = array('key1' => 'value1', 'key2' => 'value2');
$url = 'http://example.com/receive_data.php';
$options = array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-type: application/x-www-form-urlencoded',
        'content' => http_build_query($data)
    )
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);

// Receiving data in receive_data.php using POST method
$data = $_POST;
$key1 = $data['key1'];
$key2 = $data['key2'];
echo "Received data: key1=$key1, key2=$key2";
