remove final '/' char from hashtag url

I've got a situation that I won't be able to apply htaccess on, particularly this URL:

www.site.com/#hash

which triggers an important js function.

Some referrers are sending traffic to www.site.com/#hash/ <-- notice the trailing slash

I need a quick-fix solution (PHP would be my first choice, and JS second) that will strip away any final '/' from the URL while leaving any kind of hash (e.g., /#hash1, #hash2, #otherhash, etc.) intact.

I've tried a few dozen things and so far I still haven't found a good way to target/modify/remove only the '/' and nothing else.

For example, I'm pretty sure this could work:

$url = preg_replace('{/$}', '', $url);

...but I don't know how to aim it at the actual url in the browser's address bar.

And, with JS, for example, pseudocode:

if (window.location.hash.CONTAINS == '/') {window.location.hash = ''}

In this case I can't figure out how to target only the possible '/' at the end.

This is a problem that can't be solved in PHP. You must use JavaScript.

Use String.prototype.indexOf():

if (location.hash.indexOf('/') != -1) {
    // remove the slash
    location.hash = location.hash.replace('/', '');
}

If it needs to be specifically the last slash:

if (location.hash.substr(-1) == '/') {
    location.hash = location.hash.slice(0, -1);
}

Try use String.prototype.replace to do a regex substitution:

window.location.hash = window.location.hash.replace(/\/$/, '');
