Include and Require File in PHP

include File

include file is used to include the PHP, HTML, or text on multiple pages of a website.

You can insert the content of one PHP file into another PHP file (before the server executes it)with the include statement. That means you can reuse the code again and again.

It includes a specified file. It will produce a warning if it fails to find the file and execute the remaining scripts

 There are two ways to include file in PHP.

1.     include

2.     require
Advantage:
Code Reusability

      Syntax:

      include 'filename';

     Example:

   Lp.html

 <a href="#">Home</a> |
