To use the ContactsEncoder module:

1. Extend the platform-specific ContactsEncoder class

2. Instantiate the encoder

$contacts_encoder_params = new Params();
$contacts_encoder_params->api_key = 'CleanTalk API key';

$contacts_encoder = ContactsEncoder::getInstance($contacts_encoder_params);

3. Prepare the content (HTML, text, etc.)

4. Encode contact details

$encoded_content = $contacts_encoder->runEncoding('your content do encode');

5. Output the modified content

echo $encoded_content;
