How can the code provided in the forum thread be optimized for better performance and security when exchanging data between domains in PHP?
The code can be optimized for better performance and security by implementing Cross-Origin Resource Sharing (CORS) headers to allow secure data exchange between domains. This can help prevent unauthorized access to sensitive information and improve the overall efficiency of the data exchange process.
<?php
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: POST");
header("Access-Control-Allow-Headers: Content-Type");
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$data = json_decode(file_get_contents('php://input'), true);
// Process the data as needed
echo json_encode(['message' => 'Data received successfully']);
} else {
http_response_code(405);
echo json_encode(['error' => 'Method Not Allowed']);
}
