How can PHP be used to dynamically update a URL parameter based on a variable extracted from a separate file?

To dynamically update a URL parameter based on a variable extracted from a separate file in PHP, you can read the variable from the separate file, manipulate it as needed, and then append it to the URL as a parameter using the `$_GET` superglobal. This allows you to pass the variable value through the URL for further processing. 

<?php
// Read the variable from a separate file
$variable = include 'separate_file.php';

// Manipulate the variable if needed
$updated_variable = $variable + 1;

// Append the updated variable to the URL as a parameter
$url = "http://example.com/page.php?param=" . $updated_variable;

// Redirect to the updated URL
header("Location: $url");
exit;
?>
