#1 How to delete or add a slash

Suppose we have http://example.com/foo/ URL. Let's see how the function will work depending on the current permalink structure of the website.

$url = 'http://example.com/foo/';

// Permalink structure: /%postname%
$url = user_trailingslashit( $url ); // Result: http://example.com/foo

// Permalink structure: /%postname%/
$url = user_trailingslashit( $url ); // Result: http://example.com/foo/
