无限级菜单生成

无限级菜单和分类也是经常用到的功能, 这里提供一个参考案例, 具体项目可就该对应的dom结构

控制器代码

<?php
// 树状结构
$menus = [
    [
        "title" => "菜单1",
        "sub"   => [
            ["title" => "菜单1.1"],
            ["title" => "菜单1.2"],
            ["title" => "菜单1.3"],
            ["title" => "菜单1.4"],
        ]
    ],
    [
        "title" => "菜单2",
        "sub"   => [
            ["title" => "菜单2.1"],
            ["title" => "菜单2.2"],
            ["title" => "菜单2.3"],
            ["title" => "菜单2.4"],
        ]
    ],
    [
        "title" => "菜单3",
        "sub"   => [
            [
                "title" => "菜单3.1",
                "sub"   => [
                    ["title" => "菜单3.1.1"],
                    ["title" => "菜单3.1.2"],
                    [
                        "title" => "菜单3.1.3",
                        "sub"   => [
                            ["title" => "菜单3.1.3.1"],
                            ["title" => "菜单3.1.3.2"],
                        ]
                    ],
                ]
            ],
            ["title" => "菜单3.2"],
            ["title" => "菜单3.3"],
            ["title" => "菜单3.4"],
        ]
    ],
];

// 赋值给模板
$view->assign("menus", $menus);

$view->display("index");
