I'd be quite surprised if this func returned null in PHP 5.2.11 since
there's only code to return FALSE. var_dump($info); to see what it is.

I confirm (and as stated in my description) that ldap-get-entries
return NULL when there is no entries corresponding to the request filter
even when there is no error. No error. And I too think that the new
behavior comes from the change described at
http://bugs.php.net/bug.php?id=48469.

This behavior changed in 5.2.9, apparently due to the change associated
with http://bugs.php.net/bug.php?id=48469

RTFM: "Returns a complete result information in a multi-dimensional
array on success and FALSE on error. "
Your query most likely has an error, try check it with ldap_error()

Description:
------------
With PHP version < 5.2.10, if the "bad_uid" is not in the LDAP
directory and no error occured the following code return an empty array
in $info. With PHP version 5.2.10 it return FALSE $info even when there
is no error.
(simplified code)
$ldap_host="ldap.example.com";
$ldap_root="ou=people,dc=example,dc=com";
$ldap_dn="cn=admin,ou=people,dc=example,dc=com";
$ldap_password="fak3pwd";
$result = array();
$attribute_list = array("uid");
$connection = ldap_connect($ldap_host);
$link = @ldap_bind($connection, $ldap_dn, $ldap_password);
$search="(uid=bad_uid)";
$search_result = ldap_search($connection, $ldap_root, $search,
$attribute_list);
$info = ldap_get_entries($connection, $search_result);
Reproduce code:
---------------
---
>From manual page: function.ldap-get-entries#Return Values
---
$ldap_host="ldap.example.com";
$ldap_root="ou=people,dc=example,dc=com";
$ldap_dn="cn=admin,ou=people,dc=example,dc=com";
$ldap_password="fak3pwd";
$result = array();
$attribute_list = array("uid");
$connection = ldap_connect($ldap_host);
$link = @ldap_bind($connection, $ldap_dn, $ldap_password);
$search="(uid=bad_uid)";
$search_result = ldap_search($connection, $ldap_root, $search,
$attribute_list);
$info = ldap_get_entries($connection, $search_result);
Expected result:
----------------
$info :
Array
(
)
Actual result:
--------------
$info :
