How can include mechanisms be utilized to share variables between PHP files?

To share variables between PHP files, you can use mechanisms like sessions, cookies, or include files. One common way is to use include files to define variables in one file and then include that file in other PHP files where you need access to those variables. 

// variables.php
<?php
$sharedVariable = "Hello, world!";
?>

// index.php
<?php
include 'variables.php';
echo $sharedVariable; // Output: Hello, world!
?>

// otherfile.php
<?php
include 'variables.php';
echo $sharedVariable; // Output: Hello, world!
