Regex: Fix duplicate slashes without affecting protocol

Lets say you want to fix a URL that looks like:

https://www.example.com/my/path//to-file.jpg

Using a string replace or a simple regex could incorrectly fix the double slashes following the protocol. We can fix that by using a negative lookbehind.

(?<!:)/+

For PHP:

<?php$url = 'https://www.example.com/my/path//to-file.jpg';$str = preg_replace('#(?<!:)/+#im', '/', $url);// https://www.example.com/my/path/to-file.jpg

For Javascript:

let url = 'https://www.example.com/my/path//to-file.jpg';url.replaceAll(/(?<!:)\/+/gm, '/');// "https://www.example.com/my/path/to-file.jpg"
