Description:
------------
Function file_get_contents() does not follow 301 and 302 redirects sub apache module.

It returns following:
--8< -----------------------
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
<A HREF="http://www.google.com/">here</A>.
</BODY></HTML>
--8< -----------------------

We got this situation on a 20 servers and even on php-5.2.13, but in the same time it works on others servers with same configuration. 

Mystery starts when we run this script from command line. It works fine with cli, wich is compiled with same options and use same php.ini.


Test script:
---------------
<?php
echo file_get_contents("http://google.com");


Expected result:
----------------
file_get_contents should follow redirects.

Actual result:
--------------
Now it doesn't in some cases.

The redirections are followed for me both in the CLI and Apache SAPIs; I can't see any obvious reason why one would be different to the other.

Immediate thoughts:

- Does your Apache script set any context options at any point? There is a HTTP context option called "max_redirects" which controls this behaviour -- if it's set to 0, then redirects aren't followed.

- Did either (or both) builds have --with-curlwrappers enabled at build time? You can check that in the "Configure Command" line in phpinfo().

Thank you for reply.
Well same situation with max_redirects. It works only for cli. It seems SAPI ignore it and set to zero or 1.

And yes both versions are comiled with curlwrappers. You can see phpinfo() here 
isonet.ru/test/pi.php


I would really appreciate any other thoughts or suggestions.
Thank you.

As a workaround we have recompiled php without --with-curlwrappers option and file_get_contents started to work as it should.

We have latest curl on that server curl-7.15.5-9.el5 here is version info:
curl 7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5

cataphract, any idea on how to reproduce this ? or what was the problem ? I'm 
trying to fix as much bug as possible in ext/curl but can not reproduce this one.

I've had the same bug. My PHP build was compiled with --with-curlwrappers and it didn't follow "Location: " HTTP headers. Then I recompiled it without --with-curlwrappers and it just worked as expected. So the problem must be with the code of Curl Wrapper. After a research, I couldn't find any configuration place for curl wrapper i.e. in php.ini or somewhere else. So the "CURLOPT_FOLLOWLOCATION" setting may be hardcoded with Curl Wrapper to "off". I don't have any further information, just wanted to give some clue.

curlwrappers have been removed in PHP-5.5
