How to include headers in a cURL request in PHP?

To include headers in a cURL request in PHP, you can use the CURLOPT_HTTPHEADER option in the curl_setopt function. Here's an example:

// Initialize cURL
$ch = curl_init();

// Set the URL
$url = 'https://example.com/api'; // Replace with your desired URL

// Set the headers
$headers = array(
    'Content-Type: application/json', // Replace with your desired headers
    'Authorization: Bearer Your_Access_Token'
);

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

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

// Close cURL
curl_close($ch);

// Handle the response
if ($response === false) {
    // Request failed
    echo 'Error: ' . curl_error($ch);
} else {
    // Request successful
    echo $response;
}

In this example, the CURLOPT_HTTPHEADER option is set using the curl_setopt function along with an array of headers. You can replace the example headers with the headers you need for your specific request.
