What are the potential pitfalls of using if-conditions in PHP to differentiate between different pages or functionalities?

Using if-conditions to differentiate between different pages or functionalities can lead to bloated and hard-to-maintain code, especially as the number of conditions grows. A better approach is to use a routing system, such as a front controller pattern, to handle requests and direct them to the appropriate controller or method. This helps to keep the code organized, modular, and easier to extend or modify in the future. 

// Example of using a front controller pattern to handle requests

// index.php
$request = $_SERVER['REQUEST_URI'];

switch ($request) {
    case '/page1':
        include 'controllers/page1Controller.php';
        break;
    case '/page2':
        include 'controllers/page2Controller.php';
        break;
    default:
        include 'controllers/errorController.php';
        break;
}

// page1Controller.php
// Controller logic for page 1

// page2Controller.php
// Controller logic for page 2

// errorController.php
// Controller logic for error page
