file_get_contents(): No such host is known error

Question

I am using the file_get_contents function to get the URL into a string:

$contents = file_get_contents("http://google.com");

But, I am getting the following error:

file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: No such host is known.

How can I solve this in my localhost?

Solution 1

Your "localhost" cannot resolve the name google.com to an ip address, which means your machine doesn't/can't reach a valid dns server.
This probably doesn't only affect php. Try ping google.com on the console of that machine. Does this complain about the unknown host, too?
The steps necessary to solve the problem depend on what your "localhost" is (operating system, flavour/distribution, ...) and how it is connected to the internet.

Solution 2

It is because you need to turn on allow_url_fopen in php.ini

I think this may be DNS or firewall issue. Can you check if you can ping google.com from that host?

ping google.com works in command line but getting same issue.

That's not correct - if that was the case the server would return someting like "failed to open stream: no suitable wrapper could be found" or "URL file-access is disabled in the server configuration"

ping google.com works in command line but getting same issue

allow_url_fopen is Already ON but still not working
