<?php

use mysqli;
use Illuminate\Http\Request;
 
class DataController extends Controller
{
    public function getDataFromDatabase()
    {

        $mysqli = new mysqli('localhost', 'root', '', 'storage');
 

        $result = $mysqli->query("SELECT * FROM ads");
 

        $data = [];
        while ($row = $result->fetch_assoc()) {
            $data[] = $row;
        }
 

        return $data;
    }
    /**

    public function __invoke(Request $request)
    {
        require 'project/vendor/predis/predis/autoload.php';
        Predis\Autoloader::register();

        $redis = new Predis\Client(array(
            "scheme" => "tcp",

        $redis->connect('127.0.0.1', 6379);
 

        $data = $redis->get('data');
 

        if (!$data) {

            $data = $this->getDataFromDatabase();
 

            usort($data, function ($a, $b) {
                return $b['CPM'] <=> $a['CPM'];
            });
 

            $data = $data[0];
 

            $redis->set('data', $data, 60);
        }
 

        return view('ads', ['data' => $data['CPM']]);
    }
}

Trying to import predis library, but getting error

Answer 1

To the best of my knowledge, laravel under the hood already know how to handle connecting to redis through the client you configured. You dont need to manually load predis in your controller. Your invoke method can be like this:

/**
 * Handle the incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function __invoke(Request $request)
{
    $redis = Redis::connection();

    $data = $redis->get('data');


    if (!$data) {

        $data = $this->getDataFromDatabase();


        usort($data, function ($a, $b) {
            return $b['CPM'] <=> $a['CPM'];
        });


        $data = $data[0];


        $redis->set('data', $data, 60);
    }


    return view('ads', ['data' => $data['CPM']]);
}

You ll have to do use Illuminate\Support\Facades\Redis; in your use statement
