How to ping archive.org to save my website
<?php
$url = "https://example.com"; // Replace with your site URL
$apiUrl = "https://web.archive.org/save/" . urlencode($url);
$response = file_get_contents($apiUrl);
if ($response !== false) {
echo "Site successfully pinged to archive.org!";
} else {
echo "Failed to notify archive.org.";
}
?>I can also use the Wayback Machine’s bookmarklet to save any page by using this bookmarklet in the browser.
Best Practices
• Use the API sparingly to avoid overwhelming the service.
• Ensure your site adheres to robots.txt guidelines, as Archive.org respects these rules.
• If the page is private or restricted, the Wayback Machine may not archive it. Make sure the content is publicly accessible.
This way, you can keep your site’s updates reflected on the Wayback Machine!
List of Country codes in an array for PHP
This is a complete (AFAIK) array that includes all the countries recognized with ISO 3166-1 alpha-2 codes as used by Flagcdn.com. You can use these codes directly to reference flag images, for example, https://flagcdn.com/w320/us.png for the United States flag.
List converted from https://flagcdn.com/en/codes.json
Might need a little tweaking depending on its use. Sometimes country names don't match. It's usually counties with long names like Côte d'Ivoire (Ivory Coast).
