file_get_contents（https：// url）失败[关闭]

Question

On my Ubuntu 12.04 server running PHP 5.5 on Lighttpd I have

• allow_url_fopen On
• allow_url_include On
• OpenSSL Support Enabled
• OpenSSL Library/Header Version 1.0.1 14 Mar 2012

I am not sure this is right but I also put in extension=openssl.so in my php.ini file and rebooted by server. I see no untoward error messages in my logs.

Nevertheless I still get failed to open stream: Connection timed out. The same URL without https works just fine. Am I missing something

Answer 1

As someone said above this is a network issue. Actually, I was wrong when I said that http://exmaple.com worked whilst https://example.com did not. I run four servers, call them A, B, C & D at different global locations - two in the US, one in Europe and one in Asia. The URL that I am trying to reach is for another server in the US. After posting this question and reviewing the various comments I explored matters a bit more and discovered that my file_get_contents call was failing only from the Asian server. TraceRoute revealed that the Asian server is simply unable to locate the one I want to reach. So as someone here said - this is a network issue. I am posting this answer so anyone who runs into this thread in quest of a solution to a similar problem realizes that this might well be the problem rather than a PHP configuration thing.
