What configuration adjustments may be necessary to ensure PHP files display properly?

To ensure PHP files display properly, you may need to adjust the configuration settings in your server. One common adjustment is to make sure that the server is configured to parse PHP files correctly by setting the appropriate file extensions and handlers. Additionally, enabling error reporting can help identify any issues that may be preventing the PHP files from displaying as expected.

// Example of configuring PHP file extensions and handlers in Apache server
<FilesMatch \.php$>
    SetHandler application/x-httpd-php
</FilesMatch>

// Enable error reporting in PHP
error_reporting(E_ALL);
ini_set('display_errors', 1);
