hi cahva i've just proved this code and it returns a "string(0) "" "

i have write this in the library:

Code:

$this->_safe_mode = var_dump(ini_get("safe_mode"));

instead of:

Code:

$this->_safe_mode = ((boolean)@ini_get("safe_mode") === FALSE) ? FALSE : TRUE;

was it what i must did?

my code for sending mail is very simple,and is this:

Code:

$this->load->library('email');
            $this->email->from('[email protected]');
            $this->email->to('$email');//post data from input
            $this->email->subject('asd asd');
            $this->email->message('ok is arrived');
            $this->email->send();
