Fatal error: Class 'Predis\Client' not found

Question

I'm using codeigniter framework. I want to use redis on my project.

to do this I find this library:

https://packagist.org/packages/predis/predis

I installed it with composer.

now I want to use it:

  $client = new Predis\Client();

but I got this message:

Message: Class 'Predis\Client' not found

I set up these configs:

$config['composer_autoload'] = '/vendor/autoload.php';
$config['composer_autoload'] = TRUE;

my OS is windows 7. somewhere says I should install redis on my windows because I'm using localhost. yeah?

updated

How can I load this library? I just installed with composer. — S.M_Emamian, Jul 19 '17 at 05:35

`This library is deprecated. We recommend migrating to Predis` — S.M_Emamian, Jul 19 '17 at 05:45
add this line to your controller constructor `require 'Predis/Autoloader.php';` — Yaseen Ahmad, Jul 19 '17 at 05:58

Move composer.json, composer.lock and vendor inside application directory and leave $config['composer_autoload'] = '' empty. It is recommended since that way someone won't be allowed reading what external libraries/packages your application uses. Also APPPATH.'vendor' is default CI location (by docs).

If you for some reason want to have composer.json in publicly accessible location, try your existing configuration with this change:

$config['composer_autoload'] = FCPATH.'vendor/autoload.php';

Also, have you put

use Predis\Client as PredisClient;//for distinctive use of Client word in case of Guzzle, other libs, etc.

before controller class code? After that you can use it as

$client = new PredisClient();

Check if all of this works.
