Controller code

<?php
    class SendEmail extends Controller
    {
        
        function __construct()
        {
            parent::__construct();
            $this->load->library('email'); // load the library
        }
        
        function index()
        {
            $this->sendEmail();
        }
        
        public function sendEmail()
        {
            // Email configuration
            $config = Array(
                'protocol' => 'smtp',
                'smtp_host' => 'smtp.gmail.com.',
                'smtp_port' => 465,
                'smtp_user' => 'xxxx', // change it to yours
                'smtp_pass' => 'xxxx', // change it to yours
                'mailtype' => 'html',
                'charset' => 'iso-8859-1',
                'wordwrap' => TRUE
            );
            
            $this->load->library('email', $config);
            $this->email->from('xxxx', "Admin Team");

            $this->email->cc("xxxx");
            $this->email->subject("This is test subject line");
            $this->email->message("Mail sent test message...");
            
            $data['message'] = "Sorry Unable to send email...";
            if ($this->email->send()) {
