PHP error: php_network_getaddresses: getaddrinfo failed: (while getting information from other site.)

Question

Trying to get information from an external source, I\'m receiving the following error:

Warning: php_network_getaddresses: getaddrinfo

Answer 1

I faced this issue, while connecting DB, the variable to connect to db was not defined.

Cause: php tried to connect to the db with undefined variable for db host (localhost/127.0.0.1/... any other ip or domain) but failed to trace the domain.

Solution: Make sure the db host is properly defined.
