Programmatically set html link to localhost or AWS domain

Question

Consider:

"if you do want to change your password, simply click: 
<a href="http://localhost:8888/index.php?'.http_build_query (array_merge($_GET, array ('action'=>'checkcredentials', 'reset_term' => $term)))..."

Now consider:

"if you do want to change your password, simply click: 
<a href="http://my.domain/index.php?'.http_build_query (array_merge($_GET, array ('action'=>'checkcredentials', 'reset_term' => $term)))..."

What I would like to do is replace the localhost:8888 part of the example with some magic that will determine whether the script should point to localhost:8888 or my.domain. I deploy the application on AWS, although I have a domain pointed at my AWS instance, and I develop and test on my local machine (hence localhost).

In summary, what do I need to replace localhost:8888 with that will determine itself where to point the URL?

Answer 1

You can try

<a href="<?php echo $_SERVER['SERVER_NAME']; ?>/index.php?'>

Or you can edit the host file and add http://my.domain/ and point it to localhost
