foreach循环计数功能总计

Question

我想在count variable上$nb_quota_lic_simples总共foreach

在foreach ($equipes as $equipe) { $nb_quota_lic_simples = $equipe->catg_equipe->nb_licences; } dd($nb_quota_lic_simples); 我检查我有多少免费许可证，如果有很多设备，我想获得许可证的总数。希望有人帮助我。非常感谢提前！

其实我有：

尝试这样的事情

    $total = 0;
    foreach ($equipes as $equipe) {
        $total += $equipe->catg_equipe->nb_licences;               
    }
    dd($total);
