If you're having problems with fopen("url...") but you can run 'host url' in a shell window and get the correct lookup, here's why...
This has had me banging my head against it all day - finally I found the answer buried in the bug reports, but figured it should really be more prominent!
The problem happens when you're on an ADSL line with DHCP (like our office)... When the ADSL modem renews the DHCP lease, you can also switch DNS servers, which confuses apache (and hence PHP) - meaning that you can't look up hosts from within PHP, even though you canfrom the commandline.... The short-term solution is to restart apache.
You'll get "php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in ..." messages as symptoms. Restart apache, and they're gone :-)

如果您在使用 fopen("url...") 时遇到问题，但您可以在 shell 窗口中运行 'host url' 并获得正确的查找，这就是为什么...
这让我一整天都在头疼——最后我找到了隐藏在错误报告中的答案，但我认为它真的应该更加突出！
当您使用带有 DHCP 的 ADSL 线路（例如我们的办公室）时，问题就会发生……当 ADSL 调制解调器续订 DHCP 租约时，您还可以切换 DNS 服务器，这会混淆 apache（以及 PHP）——这意味着您可以即使您可以从命令行中查找主机，也不要从 PHP 中查找主机......短期解决方案是重新启动 apache。
您将收到“php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in ...”消息作为症状。重新启动apache，它们就消失了:-)

make sure that website can be reached from you server. also make sure that you are using has a proper DNS server setup.
确保可以从您的服务器访问该网站。还要确保您使用的 DNS 服务器设置正确。
if you are sure that website is working ... try modifying the /etc/hosts file and add the website's IP for test purposes, then try to figure out why it doesn't solve the domain.
如果您确定该网站正在运行...尝试修改 /etc/hosts 文件并添加网站的 IP 以进行测试，然后尝试找出它无法解决域的原因。

The Domain can not be resolved to it's IP address.
域无法解析为其 IP 地址。
If you have your DNS running local, try restarting it. If not, check your DNS or add a different server to /etc/resolve.conf (i.e. nameserver 8.8.8.8).
如果您的 DNS 在本地运行，请尝试重新启动它。如果没有，请检查您的 DNS 或将不同的服务器添加到 /etc/resolve.conf（即名称服务器 8.8.8.8）。
You can also add the domain as a static entry in your hosts file:
您还可以将域添加为 hosts 文件中的静态条目：
On your linux server add the DNS information to your /etc/hosts file using:
在您的 linux 服务器上，使用以下命令将 DNS 信息添加到您的 /etc/hosts 文件中：
echo '127.0.0.1 www.otherdomain.com' >> /etc/hosts
echo '127.0.0.1 www.otherdomain.com' >> /etc/hosts
…where 127.0.0.1 is the IP address of your website and www.otherdomain.com the domain name your using.
...其中 127.0.0.1 是您网站的 IP 地址，www.otherdomain.com 是您使用的域名。
You can find the IP address of any domain using nslookup, i.e
您可以使用 nslookup 查找任何域的 IP 地址，即
nslookup www.otherdomain.com
nslookup www.otherdomain.com
