PHP ini file_get_contents external url

Question

I use following PHP function:

file_get_contents('http://example.com');

Whenever I do this on a certain server, the result is empty. When I do it anywhere else, the result is whatever the page's content may be. When I however, on the server where the result is empty, use the function locally - without accessing an external URL (file_get_contents('../simple/internal/path.html');), it does work.

Now, I am pretty sure it has something to do with a certain php.ini configuration. What I am however not sure about is, which one. Please help.

Answer 1

The setting you are looking for is allow_url_fopen.

You have two ways of getting around it without changing php.ini, one of them is to use fsockopen(), and the other is to use cURL.

I recommend using cURL over file_get_contents() anyways, since it was built for this.
