file_get_content错误？

Question

Everything is working fine on localhost but first I host the website after up and downs and overcoming over I got stuck at this problem:

file_get_contents(http://....): failed to open stream: Connection timed out

I have not used file_get_function anywhere in my code but it is giving the error. Where is this coming from?

What does Connection time out mean? I checked on SOF but I get more and more confused. Any help will be appreciated!

Can anyone give a detailed explanation or link?

Answer 1

There could be two main reasons for this:

• Your server cannot resolve the domain name (try nslookup from shell) - if this is the problem, you can try to set Google nameservers (8.8.8.8, 8.8.4.4)
• There are firewall restrictions, which do not allowed to make inbound/outbound connection from your server

You can try out a cURL connection instead, maybe this helps.

Answer 2

file_get_contents() does not deal with slow network connections or redirects for getting remote files. You can use fsockopen() which allow a custom connection timeout value try to use cURL

Answer 3

See this TIP in the php manual

A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.

If your live site does not have allow_url_fopen = On then this function will not allow you to use url's
