Unique instance of service

Hey,

I want to make a single instance of a service to store class attributes between Controllers

Exemple :
In /ThirdParty i create class MyService

PHP Code:

<?php

namespace App\ThirdParty;

class MyService {

    protected $idRandom= 0;

    public function __construct() {
        $this->idRandom =random_int(0, 10000);
    } 

    public function getIdRandom(){
        return $this->idRandom;
    }

    public function setIdRandom($code = ''){
        $this->idRandom = $code;
    }
} 


In Config/Services :

PHP Code:

<?php

namespace Config;

use CodeIgniter\Config\BaseService;
use App\ThirdParty\MyService;

/**
 * Services Configuration file.
 *
 * Services are simply other classes/libraries that the system uses
 * to do its job. This is used by CodeIgniter to allow the core of the
 * framework to be swapped out easily without affecting the usage within
 * the rest of your application.
 *
 * This file holds any application-specific services, or service overrides
 * that you might need. An example has been included with the general
 * method format you should use for your service methods. For more examples,
 * see the core Services file at system/Config/Services.php.
 */
class Services extends BaseService
{
    // public static function example($getShared = true)
    // {
    //     if ($getShared)
    //     {
    //         return static::getSharedInstance('example');
    //     }
    //
    //     return new \CodeIgniter\Example();
    // }

    public static function myServ($getShared = true){
        if ($getShared)
        {
        return static::getSharedInstance('myServ');
        }
        return new MyService();
    }
} 


In Controllers folder :

PHP Code:

<?php
namespace App\Controllers;

use App\Libraries\InstagramLibrary;

class ControllerOne extends BaseController
{

    public function __construct() {
        $this->myServ = \Config\Services::myServ();
    }

    public function index()
    {
        echo $myServ->getIdRandom();
    } 


And 

PHP Code:

<?php
namespace App\Controllers;

use App\Libraries\InstagramLibrary;

class ControllerTwo extends BaseController
{

    public function __construct() {
        $this->myServ = \Config\Services::myServ();
    }

    public function index()
    {
        echo $myServ->getIdRandom();
    } 


And when i go to the page the idRandom are not the same ... any explication ?

random is rando what do you expect ? !!!!!!  can be same result

random is rando what do you expect ? !!!!!!  can be same result

I want to have the same result into the 2 controllers :
On the first call of a controller : the service is init so the idRandom take a value between 0 and 10 000 for example 999
On a second call of the controller or another one which use this service i want to get the same instance to get the same idRandom in my example 999

Okay first thanks u r using ci4
You should store init value in datebase or session for second ctl
This is not pussible call two ctl diffrent times then have same reult

use static variables.

What did you Try? What did you Get? What did you Expect?

If the controllers are called on separate requests, that is never going to work how you want it to.

'$this->idRandom =random_int(0, 10000);' is called for every request.

If you need to persist something between requests, use sessions or a database.

Okey thanks a lot for your return ! I'll use database

Database would work fine but depending on the actual use of this scenario you may want to consider Session or Cache as more appropriate short-term persistence solutions.

Thanks MGatner, session isn't the best solution because the goal is to have a unique instance of my service for all my clients.

The service's goal is to connect to a back-office. The connection is available for application not for users. So the session is specific for user
