How can htaccess files be utilized to customize error pages in PHP websites?

To customize error pages in PHP websites using htaccess files, you can use the ErrorDocument directive to specify the custom error page for different HTTP status codes. This allows you to create personalized error pages for 404 Not Found, 403 Forbidden, and other error codes. ```apache # Custom error pages ErrorDocument 404 /errors/404.php ErrorDocument 403 /errors/403.php ``` In this example, the htaccess file is configured to redirect users to the specified PHP files located in the "errors" directory for the 404 Not Found and 403 Forbidden errors. Make sure to create the custom error pages in the specified location with the appropriate content.
