How can PHP be used to troubleshoot URL resolution issues in MediaWiki installations?

To troubleshoot URL resolution issues in MediaWiki installations using PHP, you can check the configuration settings related to URL rewriting and ensure that the correct rewrite rules are in place. You can also use PHP to debug and print out the resolved URL to see if it matches the expected format.

// Check if URL rewriting is enabled
if ($_SERVER['REQUEST_URI'] !== $_SERVER['SCRIPT_NAME']) {
    echo "URL rewriting is enabled";
}

// Print out the resolved URL
echo "Resolved URL: " . $_SERVER['REQUEST_URI'];
