Currently setting up a backup solution that sends a database dump and some other files from a Wordpress network to a NAS on my LAN, via WebDAV. I have installed PHP WebDAV on my web server and the basic code to get that that to work is:
webdav_connect('http://webdav.example.com/dav', 'davuser', 'davpassword');
webdav_put('/your/nice/thing.txt', $data);
webdav_close();
The issue is, my NAS requires this connection to be done via HTTPS, so in a web browser you'd see a warning which you can ignore, but PHP gives the following warning and the code fails:
Warning: webdav_put() [function.webdav-put]: Server certificate verification failed: certificate issued for a different hostname, issuer is not trusted in /var/www/vhosts/blah/blah/blah.php on line 5
Is there a way in which I can ask PHP to ignore this, or will I need to obtain an SSL certificate? The domain name used for accessing the WebDAV service on my NAS is one provided by Dynamic DNS if that makes a difference.
