Condition in controller laravel

I have this code in my Laravel controller 

public function index($id=false) {
    //get resto by name
    $resto_nom = DB::table('restos as r')
        ->JOIN('produit as p', 'p.r_id', '=', 'r.r_id')
        ->JOIN('categorie as c', 'c.ca_id', '=', 'p.ca_id')
        ->WHERE('r.r_nom', $id)
        ->WHERE('p.po_etat', 1)
        ->get();

    foreach ($resto_nom as $r):
        $r_nom = $r->r_nom;
        $r_description = $r->r_description;
        $r_specialite = $r->r_specialite;
        $meta = $r_nom.', '.$r_specialite.", restaurant NosRepas, repas";
        $description = $r_nom.' - '.$r_specialite.'. '.$r_description;
    endforeach;

    if($id != $r_nom){
        return view('frontend.pages.resto', compact('meta', 'description', 'resto_nom'));
    }else{
        return view('frontend.pages.resto', compact('meta', 'description', 'resto_nom'));
    }
}

I have error after Undefined variable: r_nom My goal is displaying if the value found is correct so view display and so incorrect it returns 404 not found.

You have to set the variable before foreach, otherwise it will be available only inside the loop. Try this:

$r_nom = null;
foreach ($resto_nom as $r):
    $r_nom = $r->r_nom;
    $r_description = $r->r_description;
    $r_specialite = $r->r_specialite;

    $meta = $r_nom.', '.$r_specialite.", restaurant NosRepas, repas";
    $description = $r_nom.' - '.$r_specialite.'. '.$r_description;
endforeach;
