How can variables in one PHP file be accessed in another PHP file?

To access variables from one PHP file in another PHP file, you can use include or require statements to bring the first file into the second file's scope. This allows you to access the variables defined in the first file as if they were defined in the second file. Make sure to include the first file before trying to access its variables in the second file. 

// File1.php
$variable = "Hello, world!";

// File2.php
include 'File1.php';
echo $variable; // Output: Hello, world!
