file get contents php network getaddresses getaddrinfo failed

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

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

Warning: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in line #.

Yesterday everything was fine, so what happened to this script, which is not working and gives me the error above? Any solution or hint to solve this problem?

I also tried by converting DNS to IP but then I get the warning: failed to open

I tried to remove the http but am still getting the above error.

It’s because you can’t resolve the host name Maybe DNS problems, host is unreachable.

try to use IP address instead of host name. ping this host name. nslookup it.

In the following httpd.conf file, configure the ServerName properly.

This resolved similar issue I was facing.

In my case(my machine is ubuntu 16), I append /etc/resolvconf/resolv.conf.d/base file by adding below ns lines.

then run the update script,

I would imagine that the caching DNS servers you’re using aren’t behaving properly (or the DNS server for the domain you’re resolving isn’t working properly). You can try to fix the former possibility.

Do you have at least 2 name servers registered on your network adapter? You could always swap your computer over to use a different caching DNS server to rule this out. Try Google’s:

If you can discount transient outages on the remote server you are trying to connect to, then that just leaves the local network config as a problem.

Using the IP address instead of the hostname is only going to work for the default domain on the remote host.

What happens when you try using www.google.com (or its IP address)? If you stil can’t connect, then its something to do with the network between your server and the outside world.

Although this is a old thread, I have come across the same error recently while running nslookup in CentOS 7 and google search led me to some of the discussions in SO including this one. However, adding the nameservers entries to /etc/resolv.conf alone did not help as the nameserver values in resolv.conf were overwritten by the NetworkManager with the default DNS nameservers that are in the eth profile associated to the ethernet IP config.

As mentioned by @m-canvar, set the following entries in /etc/resolv.conf

To prevent overwriting these entries by NetworkManager, there are two two approaches:

Option 1: Either set NM_CONTROLLED=no in the eth profile associated to the IPv4/IPv6 profile.

Option 2: Disable NetworkManager service from running.

More details can be referred in my post about this error and solution.

php_network_getaddresses: getaddrinfo failed: Name or service not known

Here is a snippet of my code

When I run it, it outputs:

unable to connect to www.mydomain.net/1/file.php:80 (php_network_getaddresses: getaddrinfo failed: Name or service not known

I can’t figure out why. Any help would be greatly appreciated.

If you are trying to access a remote URL, then file_get_contents() is your best bet. You can provide a full URL to that function, and it will fetch the content at that location using a normal HTTP request.

That leaves any error handling up to you of course, but it would mean that you wouldn’t waste time reading the response.

I had a similar problem on my local testserver and local testdomains e.g.: www.testdomain.loc with the function GetImageSize() ;

Solved it by adding the hostname in the hosts file on the local server:

In the file /etc/hosts I added:

Hope this helps anyone

If you only want to submit GET data to the URL, you should use something straightforward like file_get_contents();

Had such a problem (with https://github.com/PHPMailer/PHPMailer), just reload PHP and everything start worked

for Centos 6 and 7:

you are trying to open a socket to a file on the remote host which is not correct. you could make a socket connection (TCP/UDP) to a port number on a remote host. so your code should be like this:

if you are trying to create a file pointer resource to a remote file, you may use the fopen() function. but to do this, you need to specify the application protocol as well.

PHP provides default stream wrappers for URL file opens. based on the schema of the URL the appropriate stream wrapper will be called internally. the URL you are trying to open does not have a valid schema for this solution. make sure there is a schema like «http://» or «ftp://» in it.

so the code would be like this:

Besides I don’t think the HTTP stream wrapper (that handles actions on file resources on URLs with http schema) supports writing of data. you can use fread() to read contents of a the URL through HTTP, but I’m not sure about writing.

EDIT: from comments and other answers I figured out you would want to send a HTTP request to the specified URL. the methods described in this answer are for when you want to receive data from the remote URL. if you want to send data, you can use http_request() to do this.

php_network_getaddresses: getaddrinfo failed error in Docker’s adminer

I have problem with access to adminer in my docker container with laravel 5/mysql app. I got error :

I got different ports for app and db container.

Usage with external server You can specify the default host with the ADMINER_DEFAULT_SERVER environment variable. This is useful if you are connecting to an external server or a docker container named something other than the default db.

In console of my app I run command

with unused in my apps port and this command was not succesfull anyway, as I got the same error trying to log to adminer https://imgur.com/a/4HCdC1W.

In my docker-compose.yml :

I rebuilded the app but I failed to login into adminer : https://imgur.com/a/JWVGfBA

I run in console of my OS pointing to other unused 8089 port:

But again error logining to adminer to 8089 port, but the error message was different :

I suppose yes, as after I rebuilded the container I entered into the box and see “root” in console output:

MODIFIED BLOCK # 4

I remade this docker, I set default names of containers(I suppose that it raise some confusion) and I set image: composer:1.8 latest version So in my docker-compose.yml :

and in web/Dockerfile.yml :

But anyway after rebuilding of the project and connecting to adminer with http://127.0.0.1:8082 url I got error:

P.S.: I have other laravel 5.0/php:5.6 / image: composer:1.6 / mcrypt installed docker project on the same local server of my laptop, which works ok for me and I can enter adminer and can login to db from this app. This docker project has files:

MODIFIED BLOCK # 5: with defined :

Running http://127.0.0.1:8082/ I got error in browser :

While trying app url http://127.0.0.1:8081/public/ I got error :

Try with phpMyAdmin 🙂

So what you should have done is, Before starting docker container you should have defined the environment variable either by defining it in compose file or exporting it in shell as shell variable before running docker-compose or should have used env file or by using ENV instrction in dockerfile. (These are all the possible ways of defining environment variables and I’ve listed all of them the method that comes first takes priority. refer this for more info).

So the proper docker-compose.yml file should be as follows.

Now coming to the next point I see that from your discussions you have concluded that removing volumes from the db container fixed your problem. But actually not. How?

First let me explain why volume is used here. The data generated my mysql should be stored somewhere. Docker by default runs containers in non-persistant mode, which means all the data generated by the running docker conatiner will be erased when that container is brought down/killed. So in order to persist(store/save) data we use volumes. There are different types of volumes used in docker. I encourage you to read Storage documentation of docker for more details. The type of volume used here is a bind mount which is, You bind a host directory to a docker directory and docker stores all the data directly in host machine such that even if docker container is brought down data is still preserved.

Hence if you don’t use volumes in mysql all the db changes irrespective of whatever you do, will be lost whenever the container is stopped.
