My Answer:
To call a function from functions.php in the URL in WordPress, you can create a custom endpoint using the add_rewrite_rule() function. Here's how you can achieve this:

1. Add the following code to your theme's functions.php file:

php
function custom_rewrite_rule() {
add_rewrite_rule('^folder_contents/?$', 'index.php?folder_contents=1', 'top');
}
add_action('init', 'custom_rewrite_rule');

function custom_query_vars($query_vars) {
$query_vars[] = 'folder_contents';
return $query_vars;
}
add_filter('query_vars', 'custom_query_vars');

function custom_template_redirect() {
if (get_query_var('folder_contents')) {
folder_contents();
exit;
}
}
add_action('template_redirect', 'custom_template_redirect');

function folder_contents() {
echo "Hello world";
// your code here
die();
}


2. After adding the above code, you will need to flush the rewrite rules. You can do this by going to Settings > Permalinks in your WordPress admin dashboard and clicking on the "Save Changes" button.

3. Now you can access the function by visiting http://myurl.com/folder_contents in your browser. This will trigger the folder_contents() function and display "Hello world" on the page.

Please note that directly calling functions in the URL is not a recommended practice in WordPress as it can pose security risks. Make sure to sanitize and validate any input data before using it in your functions to prevent vulnerabilities.
