Removing URL parameters using PHP

I have some links in a powerpoint presentation and for some reason when these links are clicked it adds a return parameter to the URL. Well, that return parameter caused the MVC pattern of my Joomla website to be messed up.

So, what is the effective way to remove this return parameter using PHP? ?

Solution:

1. Use parse_url() to parse the URL into an array

2. Extract the query part and use parse_str() to parse it Decomposed into an array

3. Remove the query parameters required by unset() from the array using http_build_query()

4. Rebuild the original URL

The quick and dirty thing is Use string search/replace and/or regular expressions to eliminate the value.

Regular expression such as:

$new_url = preg_replace('/&?return=[^&]*/', '', $old_url);
