Is there any way to pass variable in rememberForever callback?

Question

I have following code,

\Cache::rememberForever('Roles', function() {
    return RoleModel
        ::where('ParentRoleID' >= $CurrenctUserRoleID)
        ->get();
});

Issue is: I am getting Error

Undefined variable: CurrenctUserRoleID

Answer 1

You may try this (Notice the use of use keyword):

$CurrenctUserRoleID = 1; // Some id

\Cache::rememberForever('Roles', function() use($CurrenctUserRoleID) {
    return RoleModel
    ::where('ParentRoleID' >= $CurrenctUserRoleID)
    ->get();
});

Check the PHP manual: Inheriting variables from the parent scope.
