Node.js API from PHP

To call a Node.js API from PHP, you can use various methods such as cURL or Guzzle. Here's an example of how you can call a Node.js API from PHP using cURL:

// URL of the Node.js API endpoint
$url = 'http://localhost:3000/api'; // Replace this with your Node.js API URL

// Data to be sent to the Node.js API
$data = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

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

// Set the request method to POST
curl_setopt($ch, CURLOPT_POST, 1);

// Set the POST data
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

// Set the return transfer to true
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute the request
$response = curl_exec($ch);

// Close the cURL session
curl_close($ch);

// Output the response
echo $response;

Make sure to replace the URL with the actual endpoint of your Node.js API and modify the $data array as per your API's requirements.

Additionally, you can use the Guzzle HTTP client in PHP for making requests to the Node.js API. Here's an example:

require 'vendor/autoload.php'; // Include the autoloader

use GuzzleHttp\Client;

// Create a new Guzzle client instance
$client = new Client();

// Define the base URL of the Node.js API
$base_uri = 'http://localhost:3000/api'; // Replace this with your Node.js API URL

// Make a POST request to the Node.js API
$response = $client->request('POST', $base_uri, [
    'json' => [
        'key1' => 'value1',
        'key2' => 'value2'
    ]
]);

// Get the response body as a string
$body = $response->getBody()->getContents();

// Output the response
echo $body;

Make sure to replace the base URL with the actual endpoint of your Node.js API. Also, install Guzzle using Composer before using it in your PHP project.
