I'm trying to connect to a webservice using a PHP wrapper (which is using curl under the covers).

On my local linux machine running PHP 5.3 it works perfectly. However, when I move to a remote server (also running PHP 5.3 on Linux) the call the the webservice URL returns:

getaddrinfo(3) failed for http://server.host.com:8080/login

But when I issue a curl request from the command line, it returns the expected URL.

Can anyone shed any light on this issue?

Thanks!

  • What does dig example.com return when run on the remote host? – Ladadadada May 31 '12 at 21:51
  • What format is <URL> in - is it just the hostname, or a URL with http:// and/or anything after the hostname like a port number or trailing slash? – Shane Madden May 31 '12 at 21:54

  • It's the same reason you can't mail a package to a phone number. – David Schwartz Jun 1 '12 at 1:34

That's expected. The ping command accepts either an IP address or a hostname and not a URL. Same goes for getaddrinfo() and getnameinfo() functions.

curl works because it is supposed to work with URLs.

  • I've removed the ping statement in the question, since as you point out it doesn't have anything to do with curl failing. Thanks – user101289 Jun 1 '12 at 22:30
