What are some best practices for sending form data to a fax machine using PHP?

Sending form data to a fax machine using PHP involves converting the form data into a format that can be sent as a fax. One way to achieve this is by using a third-party fax service API that allows you to send faxes programmatically. By integrating the API into your PHP code, you can easily send the form data as a fax to the designated fax machine.

// Example code using a third-party fax service API to send form data to a fax machine
$apiKey = 'YOUR_API_KEY';
$apiSecret = 'YOUR_API_SECRET';
$faxNumber = 'RECIPIENT_FAX_NUMBER';
$formData = $_POST['form_data'];

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://api.faxservice.com/sendFax',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS => json_encode(array('apiKey' => $apiKey, 'apiSecret' => $apiSecret, 'faxNumber' => $faxNumber, 'content' => $formData)),
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json'
  ),
));

$response = curl_exec($curl);

curl_close($curl);

echo $response;
