Search for Modules according to the Permissions

I've built a function that lists all modules and submodules within the system. But I need it to be different, I need that in this same listing, just come the modules and submodules that the client has access to, rather than checking whether he has permission or not. I'll state how I did it:

Function for Listing the Modules:

public function getModulosCategoria(){
    $sql = "SELECT * FROM modulos WHERE idModuloBase = '0'";
    $consulta = $this->db->query($sql)->result();   

        foreach($consulta as &$valor){
            $sql_model = "SELECT * FROM modulos WHERE idModuloBase = '{$valor->idModulo}'";
            $valor->subModulo = $this->db->query($sql_model)->result();     
        }

    return $consulta;
}

In the listing I make the following verification:

foreach($modulo->subModulo as $submodulo){
    $permissao = "a".ucfirst($submodulo->pasta);
    if($this->permission->checkPermission($this->session->userdata('permissao'),$permissao)){
         Exibe o Link para o Modulo...

So far it's running 100%, but I need to do this differently. I want you to list all modules, just look for the allowed modules.

Set the modules of each client:
