php怎么转换成html,将PHP文件转换为HTML文件

So I want to create a rather large text area

for different price tags and by the extent of the code in the html file

I thought that proceeding with an embedded PHP with this information would

decrease the amount of code and also simplify editing for information purposes

what I want to know is how I can embed this sort of code which is in HTML now

with PHP into my Index.html

so my code which consist of a very large text is:

Products

Prices

.

Delivery

.

I want this to be in a PHP file and then embedded into my

Index file:

Sales

and I really like to know how you proceed with this

cause I cant seem to get it working.
