php - Removing a forward-slash from the tail-end of an URL

Question

The code below removes "www.", etc. from the beginning of websites that are entered into a database. It works great.

Is there a way I could use similar code to remove a forward-slash from the tail-end of a website that is entered into the same database?

$remove_array = array('http://www.', 'http://', 'https://', 'https://www.', 'www.');
$site = str_replace($remove_array, "", $_POST['site']);

Answer 1

You can pass a string of characters that you want trimmed off of a string to the trim family of functions. Also, you could use rtrim to trim just the end of the string:

$site = rtrim($site, "/");
