$img = create_captcha($vals);
$captcha_data = array(

$data['captcha']= $img;
$this->form_validation->set_rules('captcha','Captcha','required|trim');
if ($this->form_validation->run() ==FALSE){ //if any of the above validation fails
$data['title']= "DIRECTORY HELPER"; //in view $title
$data['page_header'] = '<strong>Directory helper in codeigniter</strong>';
$this->load->view('captchaHelper', $data);
}else {
$input = xss_clean($_POST['captcha']);
$word = $img['word'];
echo "word is of type: ".gettype($word);
echo br();
echo "POST is of type: ".gettype($input);
echo br(2);
echo $comp = strcmp($input, $word);
echo br();
echo ($input === $word)? 'Match!' : 'NOT A MATCH!';
}
}
I am new to codeigniter. I checked the variables are of the same type and values and yet when compare. it returns the 'NOT A MATCH' message.
