How to sort the search-result of ldap?

Hi,
I want to sort the result of ldap_search. Unfortunatelly ldap_sort() is
still not documented, so I don't have Idea how to use it. :(

http://php.net/ldap_sort/

Could anyone of you help me? My code look as follow:
>>>
$ds = ldap_connect("LDAP://domain.tld");
$r =
ldap_bind($ds, "CN=searchfoo,OU=Guests,OU=Benutzergruppen,DC=doma in,DC=tld","longpassword");
$sr = @ldap_search($ds,"OU=Benutzergruppen, DC=domain, DC=tld", "Company=" .
$strCompany);
$sr = ldap_sort($ds, $sr, 'givenname');

ldap_sort($ds, $sr, 'givenname');
$info = ldap_get_entries($ds, $sr);

ldap_close($ds);
<<<

I get following error:
Warning: ldap_sort() expects parameter 2 to be resource, boolean given
in /usr/local/www/data-dist/test/telefonliste/index.php on line 9

Warning: ldap_get_entries(): supplied argument is not a valid ldap result
resource in /usr/local/www/data-dist/test/telefonliste/index.php on line 10

What should I do?

Hi

$sr = @ldap_search($ds,"OU=Benutzergruppen, DC=domain, DC=tld",
"Company=" . $strCompany);

Here you supress the error by using @.
I might very well return false or something, because the ldap_search was
wrong.

Stop surpressing it, and you'll get more possibly usefull information.

$sr = ldap_sort($ds, $sr, 'givenname');

Why don't you do a print_r($sr) before using it?

As I'm new in PHP I didn't know about @. Now I removed it.

Now I know what was wrong!
First:
I accidentally wrote ldap_sort twice! *bang-on-head*
Second:
ldap_sort() returns boolean value, which tells us if it was success. Because
of that ldap_get_entries() doesn't get the result of ldap but boolean-value
and thus causes error.

So I have change the following line
$sr = ldap_sort($ds, $sr, 'givenname');
into
ldap_sort($ds, $sr, 'givenname');

Now it works! :)
Thank you!
