How to generate Codeigniter-2 as meaning word instead of code?

I figured out that codeigniter-2 by default can only generate captcha in alphanumeric . How can I expand it to generate as a meaningful word ?

For example:

  • morning

  • overlooking

  • and etc.

Sample code that generates captcha:

$vals = array(
                'img_path'      => './assets/captcha/',
                'img_url'       => 'http://url/assets/captcha/',
                'img_width'     => '130',
                'font_path'     => './assets/fonts/Moms_typewriter.ttf',
                'img_height'    => '33',
                'expiration'    => CAPTCHA_MAX_TIME_EXPIRATION
                );

$cap = create_captcha($vals);

Just use array

and pass the element with a loop



<?php

    $ab = array('Morning','Night','welcome','im here');

    $word = '';
    $n = 0;
    while ($n < 1)
    {
        $word .= $ab[mt_rand(0,9)];
        $n++;
    }


    $vals = array(
        'word'          => $word,
        'img_path'      => './assets/captcha/',
        'img_url'       => base_url().'assets/captcha/',
        'img_width'     => '130',
        'font_path'     => './assets/fonts/Moms_typewriter.ttf',
        'img_height'    => '33',
        'expiration'    => CAPTCHA_MAX_TIME_EXPIRATION
    );
