Function :

            'create' => array('F','W'),

                    if ($callback) {
                        return array_merge(array($first_level_key), $callback);
                    }

        return false;
    }

Concepts :

Any user get access list to menu, If every user enter to not accessible uri param, decline it.

Example :

User John Doe have list menu

  1. Products (Full Access)
  2. Report (Full Access)
  3. Menu (Read Only)

And John Doe opened https://localhost/dashboard/menu/create , by system decline it.

Expectation :

I want to search value dashboard/menu to get 'menu_access' value is R. And validate what if value R in array $dataParams['create'] alias ['F','W'] ?

Example :

Use : arrRecursiveAccessMap('dashboard/menu', 'create', $arrayStr);

Expect Result : false

CodePudding user response:

 $dataParams = array(
            'create' => array('F','W'),
            'update' => array('F','W'),
            'delete' => array('F'),
        );

$paramKeys = array_keys($dataParams);
  • You are repeating the above code snippet in every recursive call which is not needed. You can rather make this as a parameter for your function.

  • You also did return array_merge(array($first_level_key), $callback); but you said Expect Result : false. So, an array_merge is also not needed.

  • You also have this check if (is_numeric($needleOther) || in_array($needleOther, $paramKeys, true)) {, which is again not needed.


Solution:

You can simply make a function, pass the $dataParams and create key as parameters. Keep calling the same function recursively on menu_child and return true if you find the value of menu_access inside $dataParams['create'], else return false.

Snippet:

<?php

function userHasAccess($menu_rules, $dataParams, $data_param_key, $value_to_search){
    foreach($menu_rules as $menu_rule){
        if(($menu_rule['menu_link'] === $value_to_search && in_array($menu_rule['menu_access'], $dataParams[$data_param_key]))
           || userHasAccess($menu_rule['menu_child'] ?? [], $dataParams, $data_param_key, $value_to_search)){
            return true;
        }
    }
    return false;
}

var_dump(userHasAccess($arrayStr['user_rules'], $dataParams, 'create', 'dashboard/menu'));
