Create PHP code for dynamic website elements: menus (navigation), meta-tags, breadcrumbs and sitemap

PROJECT GOAL I have got a static html-template, which I'd like to extend with some dynamic elements for the: - menus (navigation) - meta-tags - breadcrumbs - sitemap The code should work with PHP 5.6 and PHP 7. It also should be based on bootstrap 4 definitions or classes (if available, e.g. breadcrumbs). LICENSE All files should become my own, so that I am allowed to use it on different projects for my customers. In order to grant that, the code has to be your own development and free from rights of third parties. FURTHER EXPLANATION I would like to have one config-file (no mysql-database) where I can define the following elements: - the names of all single menu-elements (navigation bar) - the status of every single menu-element: activated or not - the order and the level of every single menu-element - the title and description meta-tag of every page belonging to each menu-element I don't know how this might work (maybe via the definition of a constant at the top of every page), but I need a way to tell each single subpage which page it is, and then add the correct corresponding menu entries, breadcrumbs and meta-tags from the above mentioned config-file. > From these entries in that config-file should be created: 1) dynamic BREADCRUMBS which have links to the parent pages and are styled whith bootstrap: [login to view URL] 2) a dynamic SITEMAP on the page "sitemap" with links to every page and using the classes "sitemap-level-1", "sitemap-level-2" , "sitemap-level-3" etc. for a hierarchically ordered and css-stylable list. 3) and most importantly, the dynamic MENUS for all the subpages: I would like to have a menu that is automatically created on every single page. Here is an example how the menus and especially the product menu should look like as an end result and why I need the following classes: [login to view URL] - all necessary bootstrap classes used in the id="produktnavigation": collapse and navbar-collapse for the div, nav and navbar-nav for the ul - [login to view URL] for highlighting the active product group - [login to view URL]: for the active element -> these links should not contain a href-element and should not be clickable - [login to view URL]: for the parent menu-element of the active one -> these are linked and clickable - a.nav-zwei, a.nav-drei, a.nav-vier (which means translated two, three, four) for showing the different product levels with an indentation. Eventually, I have to be able to use this code for 3 differant menus on every single subpage: - "mainmenu" - "productmenu" - "footermenu" 4) on every page the matching META-TAGS (title and descriptopn) - defined in the config-file - should be automatically added.
