Hello Reader's! If you are working on PHP framework, Codeigniter then you should learn how to send mail by its functions. CI offers you the best way to configure the email and send the mail and you just have to call it on the place required.

lets see the example below:-

$this->load->library('email');
$this->email->from('your@example.com', 'Your Name');
$this->email->to('someone@example.com'); 
$this->email->cc('another@another-example.com'); 
$this->email->bcc('them@their-example.com'); 
$this->email->subject('Email Test');
$this->email->message('Testing the email class.');    
$this->email->send();
echo $this->email->print_debugger();

You can put this code in controller of model it will work perfect.
