Getting connection failed: php_network_getaddresses: getaddrinfo failed: Name or service not known

Question

Im using POST method to insert some data to db on my server.This is my connection.php file that is stored in my http://www.url.com/public_html.

Answer 1

The value you've specified for $servername is not a host name but rather a URL, or resource name. The host name would be just www.url.com.

Of course, as you've already discovered, localhost is the correct host name if the client and server reside on the same box.
