Is using rtrim() or substr() a more efficient way to manipulate URLs in PHP?

When manipulating URLs in PHP, using rtrim() is generally more efficient than substr() for removing trailing slashes. rtrim() specifically removes trailing characters from a string, making it a more direct and concise solution for this task. This can help improve code readability and maintainability. 

$url = 'https://www.example.com/page/';
$cleaned_url = rtrim($url, '/');
echo $cleaned_url;
