file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known

Question

I'm trying to download an image from a server using a PHP script on my website on xampp server.

The image is being downloaded using the function file_get_contents.

The php code for downloading on the server is:

if(isset($_GET['path']) && isset($_GET['username'])) {
    echo "path:".$_GET['path'];
    $temp = explode(".", $_GET['path']);
    $extension = end($temp);
    $fname="images/".$_GET['title'];
    $filenameIn  = $_GET['path'];
    $filenameOut = "" . $fname;
    $contentOrFalseOnFailure   = file_get_contents($filenameIn);
    $byteCountOrFalseOnFailure = file_put_contents($filenameOut,$contentOrFalseOnFailure);
}

But I'm getting this error:

Warning: file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /opt/lampp/htdocs/xampp/project/upload_art.php on line 19

Warning: file_get_contents(http://app6.pixlr.com/_temp/528afa6e2f7cc6a5b1000101.jpg): failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known in /opt/lampp/htdocs/xampp/project/upload_art.php on line 19

I have checked out all posted answers here but none seems to resolve the issue. Please help!

Answer 1

It means your server cannot connect to the outside world

This probably won't change anything given the DNS issues

So, If you have permission, try changing the name servers in your /etc/resolv.conf file to other nameservers.

Answer 2

There should be as well httpd allowed to connect outside. Check you selinux policy. this helps me to solve connection problem:

setsebool -P nis_enabled 1
setsebool -P httpd_can_network_connect 1

Answer 3

In reference to one of the comments by @DUzun, and for those like myself who are familiar with the server in general but not a computer science major, I fixed the issue on Linux/Centos6 (Plesk Onyx) by:

1) Opening /etc/resolv.conf (my file was empty)

2) Added:

nameserver 8.8.8.8
nameserver 8.8.4.4

options rotate
options timeout:3

Hopefully this helps someone out there.
