Loop through an array and build navigation menu with it

我正在尝试构建一个导航"系统"，其中类别和子类别存储在一个数组中。

这是数组：

$navigation = array(
'users' =>  array(
    'view'      =>  1,
    'edit'      =>  1,
    'delete'    =>  1,
    'list'      =>  1
),
'profiles'      =>  array(
    'view'      =>  4,
    'edit'      =>  4,
),
'projects'      =>  array(
    'new'       =>  3,
    'edit'      =>  3,
    'delete'    =>  1,
    'list'      =>  2,
    'mylist'    =>  3
)

）;

有了这个数组，我想遍历每个项目，如果用户的排名等于或低于值（1， 2， 3），则向他们显示适当的链接。但我真的不知道如何开始。

希望这足够清楚！

foreach ($navigation as $category) {
    // need to track if main categories have been output already
    $category_already_output = false;
    foreach ($category as $subcategory => $permission) {
        if ($current_user_permission_level <= $permission) {
            if ( ! $category_already_output ) {
                // output your html for this main category nav here
                $category_already_output = true;
            }
            // output your html for this subcategory here
        }
    }
}

编辑：以上假设您不想显示主类别，如果用户没有其任何子类别的权限。如果要始终显示每个主要类别，则可以将其简化为：

foreach ($navigation as $category) {
    // output main category html here
    foreach ($category as $subcategory => $permission) {
        if ($current_user_permission_level <= $permission) {
            // output your html for this subcategory here
        }
    }
}
