What are the considerations when dealing with localhost references in PHP scripts and how can they be addressed for proper functionality?

When dealing with localhost references in PHP scripts, it's important to ensure that the references are correctly pointing to the localhost server. This can be achieved by using the "localhost" keyword or the IP address "127.0.0.1" in the URLs within the script. Additionally, if the script is being run on a different server, the localhost references may need to be updated to reflect the correct server IP or domain. 

// Example of using localhost reference in PHP script
$localhost_url = 'http://localhost/myapp/index.php';

// Example of using IP address for localhost reference
$localhost_ip = 'http://127.0.0.1/myapp/index.php';
