Php 移动设备上未定义的细枝索引

我的小树枝模板引擎有问题。我不太明白发生了什么事。当我通过台式pc浏览我的页面时，一切正常，但当我使用手机时，我总是会遇到同样的三个错误

未定义索引：配置文件
未定义的索引：站点费用
未定义索引：帐户

这些是没有正确定义的线

$context['_seq'] = twig_ensure_traversable($context["profile"]);
$context['_seq'] = twig_ensure_traversable($context["site_fees"]);          
$context['_seq'] = twig_ensure_traversable($context["account"]);

这就是全部功能

 $_parent = $context['_parent'];
    unset($context['_seq'], $context['_iterated'], $context['_key'], $context['page_list'], $context['_parent'], $context['loop']);
    $context = array_intersect_key($context, $_parent) + $_parent;

    // line 84
    $context['_parent'] = $context;
    $context['_seq'] = twig_ensure_traversable($context["profile"]);

        // line 85

        } elseif ((session_get("language_id") == 3)) {

}否则{

}

}

我不明白为什么它能在我的电脑上正常工作。有人有线索吗

编辑：它在privat选项卡中尝试过，但仍然是同一个问题。这是细枝代码

您应该检查桌面上的源代码，而不是依赖您看到的内容。PHP是在服务器上呈现的，与设备无关。注意事项将出现在源代码中，但在屏幕上不可见。请在问题中添加细枝代码（通过编辑），看起来您只添加了编译后的PHP代码。错误很明显：您试图访问数组中不存在的某些索引。这可能与会话有关。尝试在桌面浏览器中打开一个专用选项卡/窗口，并检查是否也显示错误。
