I am having DNS issues with a certain target domain. I am using fopen() (but same issue with other functions) to retreive an image, but I get this error:
Warning: fopen(): php_network_getaddresses: getaddrinfo failed: No such host is known
I am able to ping or nslookup the domain from the command prompt, but for some reason php throws this error. When I try fopen('http://www.google.com', r); or other domains, all goes fine. But above mentioned domain simply won't resolve with PHP. I have flushed the DNS, restarted Apache, but still no luck..
I have tried with:
What can cause this single domain to not resolve?
This question is related to
php
fopen
getaddrinfo
Your target domain might refuse to send you information. This can work as a filter based on browser agent or any other header information. This is a defense against bots, crawlers or any unwanted applications.
It is more flexible to use curl instead of fopen and file_get_content for opening a webpage.
A weird thing I found was that the environment variable SYSTEMROOT must be set otherwise getaddrinfo() will fail on Windows 10.
Your "localhost" cannot resolve the name www.google.com, which means your machine doesn't/can't reach a valid dns server.
Try ping google.com on the console of that machine to verify this.
What had caused this error on my side was the following line
include_once dirname(__FILE__) . './Config.php';
I managed to realize it was the culprit when i added the lines:
//error_reporting(E_ALL | E_DEPRECATED | E_STRICT);
//ini_set('display_errors', 1);
to all my php files.
To solve the path issue i canged the offending line to:
include_once dirname(__FILE__) . '/Config.php';
