How can the language parameter be effectively passed through links in PHP for content switching?

To effectively pass the language parameter through links in PHP for content switching, you can use the $_GET superglobal array to retrieve the language parameter from the URL and then use it to dynamically load the appropriate content based on the selected language. 

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

// Use the language parameter to load the appropriate content
if($language == 'en'){
    // Load English content
    include 'content_en.php';
} elseif($language == 'fr'){
    // Load French content
    include 'content_fr.php';
} else {
    // Default to English content
    include 'content_en.php';
}
?>
