Function :

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
Products (Full Access)
Report (Full Access)
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

Answer 1

$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'));
