How can you dynamically set a variable in PHP through a URL parameter like index.php?language=en?

To dynamically set a variable in PHP through a URL parameter like index.php?language=en, you can use the $_GET superglobal array to retrieve the value of the parameter from the URL. You can then assign this value to a variable that you can use throughout your script to customize the content based on the language parameter. 

<?php
// Retrieve the language parameter from the URL
$language = isset($_GET['language']) ? $_GET['language'] : 'en';

// Use the $language variable to customize content based on the selected language
echo "Selected language: " . $language;
?>
