How can the URL structure localhost/app/post/1 be achieved in PHP applications and what steps need to be taken to implement this change effectively?

To achieve the URL structure localhost/app/post/1 in PHP applications, you can use mod_rewrite in your .htaccess file to rewrite the URLs. This will allow you to create user-friendly URLs that map to specific PHP scripts or functions. Additionally, you will need to parse the URL in your PHP script to extract the necessary information (e.g., post ID) for processing. 

// .htaccess file
RewriteEngine On
RewriteBase /app/
RewriteRule ^post/([0-9]+)$ post.php?id=$1 [L]

// index.php
$url = $_SERVER['REQUEST_URI'];
$parts = explode('/', $url);
$postId = end($parts);

// post.php
$postId = $_GET['id'];
// Use $postId to fetch and display the post with ID $postId
