What PHP functions or libraries can be used to handle URL routing in MediaWiki websites effectively?

In MediaWiki websites, handling URL routing effectively is crucial for managing different page requests and directing users to the correct content. One way to achieve this is by using PHP functions or libraries that can parse the requested URL and map it to the corresponding page or action within the MediaWiki framework. One popular PHP library for URL routing in MediaWiki is the "Title" class, which can be used to extract information from the requested URL and determine the appropriate page or action to display. By utilizing the methods provided by the Title class, developers can create custom routing logic to handle different types of URLs and direct users to the desired content within the MediaWiki website.

// Example of using the Title class for URL routing in MediaWiki

// Get the requested URL
$requestUrl = $_SERVER['REQUEST_URI'];

// Instantiate a Title object with the requested URL
$title = Title::newFromText($requestUrl);

// Check if the title is valid
if ($title && $title->exists()) {
    // Display the requested page or perform the corresponding action
    // For example, render the page content using $title->getContent()
} else {
    // Handle invalid URLs or display a custom error page
    // For example, redirect to the main page or show a 404 error message
}
