The PHP script is used to make a website dynamic.
The code is written within the defined PHP tags otherwise it would not execute.
With tags, you can display the final output after data manipulation e.g. listing fetch records from MySQL database in the <table>, display value in HTML element, upload image, etc.
Syntax –
Syntax – include
include "file-path";
Syntax – require
require "file-path";
Both statement use for including file but only difference is –
The require statement trigger FATAL ERROR if a file included more than once but the include statement doesn’t.
