How to get the full URL of the current page and change domain of it?

For example, the current url is:

https://example1.com/hello-world

I want to display this url under the showing article and also change the domain to:

https://newdomain.com/hello-world

Is there any way to do this?

Thank you guys a lot!

Answer 1

If it’s a page or post, then you can get its url with get_permalink().

And to change the domain, you can do some simple string replacing with str_replace.

So here’s the code:

echo str_replace( 'OLD_DOMAIN', 'NEW DOMAIN', get_permalink() );

Answer 2

A simple PHP str_replace() ought to do it. Although you don't mention where (or even why) you need this.

$oldstring = "https://www.example.com/here/there/"; 
$search_for = "example.com"; 
$replace_it = "newdomain.com"; 
$newstring = str_replace($search_for, $replae_it, $oldstring);
