Internet Archive

The Internet Archive is a non-profit organization that is building a digital library, including archival copy of much of the public web.
How to
Trigger an Archive
You can tell archive.org to crawl and archive a specific URL immediately.
$ curl -I -H "Accept: application/json" http://web.archive.org/save/{url to archive} | grep Content-Location
and you'll get a response like:
Content-Location: /web/20160715203015/http://indieweb.org
The response includes the path to the archived page on web.archive.org. Append this path to http://web.archive.org to build the final URL for the archived page.
PHP snippet to call the curl_exec() function with appropriate options/params:
$options =
array(CURLOPT_URL => ('http://web.archive.org/save/' . $url_to_save),
CURLOPT_HEADER => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array('Accept: application/json'),
CURLOPT_USERAGENT => "YOUR_CMS_NAME_HERE");
$ch = curl_init();
curl_setopt_array($ch, $options);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
You can then check $info['http_code'] for a numeric HTTP return code to see if there was an error (e.g. >= 400) and take action accordingly.
