I jave made a little mistake in my expample here is the good test file
:

<?
ini_set( "include_path", "/tmp/link" );
mkdir( "/tmp/php", 0777, true );
touch( "/tmp/php/one.php" );
symlink( "/tmp/php", "/tmp/link" );
require_once "one.php";
mkdir( "/tmp/essai" );
chroot( "/tmp/essai" );
mkdir( "/tmp/link", 0777, true );
$fd = fopen( "/tmp/link/one.php", "wb" );
?>

as you can see we just created /tmp/essai 
and /tmp/link in chrooted of /tmp/essai
and after trye to create /tmp/link/one.php fail !

It's due to the link in the include_path

Remove all those @ and you'll see the very expected error messages.

Description:
------------
fopen report no such file or directory when open in w mode.
It's seem to be related with include path with symlink as you can see
in sample

if the include path is /tmp/php all work.
but if the include path is /tmp/link ( sym link ) the script fail.

Reproduce code:
---------------
ini_set('include_path', "/tmp/link");

@mkdir("/tmp/php", 0777, true);
touch("/tmp/php/one.php");

@symlink( "/tmp/php", "/tmp/link" );

require_once "one.php";

@mkdir("/tmp/essai");
chroot("/tmp/essai" );

@mkdir("/tmp/link/interfaces", 0777, true);

$fd = fopen("/tmp/link/one.php", "wb");


Expected result:
----------------
No error and an file pointer in $fd 

Actual result:
--------------
Warning: fopen(/tmp/link/one.php): failed to open stream: No such file
or directory in /tmp/essai.php on line 16
