Include File
An external file can be included anywhere in a Php file by using the Php include function:-
The include command simply takes all the text that exists in the specified file and copies it into the file that uses the include function.
When a file is included:-
- The included file inherits the functions, classes and variables above the line on which the include occurs.
- From that point forward, all functions, classes and variables defined in the included file have the global scope.
Say we wanted to create a common menu file that all our pages will use. A common practice for naming files that are to be included is to use the ".inc" extension. Since we want to create a common menu let's save it as "menu.inc".
<a href="index.php">Home</a> -
<a href="about.php">About Us</a> -
<a href="links.php">Links</a> -
<a href="contact.php">Contact Us</a> <br />
Save the above file as "menu.inc". Now create a new file, "index.php" in the same directory as "menu.inc". Here we will take advantage of the include function to add our common menu.

Web pages that uses a common menu just need to include
'menu.inc' and all will have uniform menu.(save a lot of coding
works too)
