如何从 HTML 页面中分离 php 代码？

Question

I apologize for the such a bad question title, but I couldn't come out with something better. I will try to explain my problem in a brief manner so that this community will face less difficulty in understanding my problem.

Currently I am working on a CMS project and I am responsible for developing templates for that CMS. All the components of a template are being loaded dynamically on the basis of whether they have been activated or not in the admin panel, and they are being dynamically loaded on frontend using PHP code which is echoing the HTML code.

The problem is much related to updating and maintaining the templates as the number of templates is getting increased.

When there is some change needed to be made in the php code, then if number of templates is 1 or 3 then updating the same php code in other templates is not that difficult, but if the number templates increases like up to 10 or more than it will become a difficulty and will be time consuming.

I am looking for a way by which I can separate the php code from the HTML. So that when a change is required to be made in the php then it should be implemented once and it affects all the templates, rather than updating each templates php code.

I hope I am able to explain my problem correctly, but if still some information is missing then please let me know.

Updated question with code sample for better explanation.

In the code sample I am loading html elements based on conditions. Now if I need to make change in this php code and I have five different template which use the same code then I need to update it five times in five different files.

I am looking a for way to separate this php code from html.

PHP Include Files if you feel yourself repeating, then you can create another file and store a piece of code there, wherever you need it, import that file using include() . for more details, i would like to take a look on this http://www.phpknowhow.com/basics/include-files/
