ldap_control_paged_resultSend LDAP pagination control

Описание

bool ldap_control_paged_result ( resource $link , int $pagesize [, bool $iscritical = false [, string $cookie = "" ]] )

Enable LDAP pagination by sending the pagination control (page size, cookie...).

Список параметров

link

An LDAP link identifier, returned by ldap_connect().

pagesize

The number of entries by page.

iscritical

Indicates whether the pagination is critical or not. If true and if the server doesn't support pagination, the search will return no result.

cookie

An opaque structure sent by the server (ldap_control_paged_result_response()).

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Примеры

The example below show the retrieval of the first page of a search paginated with one entry by page.

Пример #1 LDAP pagination

<?php
     
// $ds is a valid link identifier (see ldap_connect)
     
ldap_set_option($dsLDAP_OPT_PROTOCOL_VERSION3);

     
$dn        'ou=example,dc=org';
     
$filter    '(|(sn=Doe*)(givenname=John*))';
     
$justthese = array('ou''sn''givenname''mail');

     
// enable pagination with a page size of 1.
     
ldap_control_paged_result($ds1);

     
$sr ldap_search($ds$dn$filter$justthese);

     
$info ldap_get_entries($ds$sr);

     echo 
$info['count'] . ' entries returned' PHP_EOL;

The example below show the retrieval of all the result paginated with 100 entries by page.

Пример #2 LDAP pagination

<?php
     
// $ds is a valid link identifier (see ldap_connect)
     
ldap_set_option($dsLDAP_OPT_PROTOCOL_VERSION3);

     
$dn        'ou=example,dc=org';
     
$filter    '(|(sn=Doe*)(givenname=John*))';
     
$justthese = array('ou''sn''givenname''mail');

     
// enable pagination with a page size of 100.
     
$pageSize 100;

     
$cookie '';
     do {
         
ldap_control_paged_result($ds$pageSizetrue$cookie);

         
$result  ldap_search($ds$dn$filter$justthese);
         
$entries ldap_get_entries($ds$result);
             
         foreach (
$entries as $e) {
             echo 
$e['dn'] . PHP_EOL;
         }

         
ldap_control_paged_result_response($ds$result$cookie);
       
     } while(
$cookie !== null && $cookie != '');

I was able to get these functions to work successfully with Active Directory.  When I first tried it, ldap_search kept returning a Not Supported reply from the server.  I finally figured out that I needed to include

ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

in my code, so that AD would let me page results.  Make sure you're using a compatible protocol.

Hope this note helps someone else.

Paged results, as specified in the RFC 2696, does not allow to get over the server sizeLimit. The RFC clearly states "If the page size is greater than or equal to the sizeLimit value, the server should ignore the control as the request can be satisfied in a single page".
With OpenLDAP, you will not get more than the sizeLimit number of entries with paged results.

You may need to do an ldap_bind before running ldap_control_paged_result to get this to work:

$conn = ldap_connect("you_ip");
ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_bind("your_connection_info");       
ldap_control_paged_result($conn, $pageSize, true, $cookie)

Without doing an ldap_bind, I kept getting the error "Critical extension is unavailable". I don't if this is standard knowledge, but knowing this would have saved me days of frustration.

If you did a paged search operation and want to do any other read operation on LDAP, you need to reset it, otherwise you will experience LDAP errors (code 12, for instance).

<?php 

ldap_control_paged_result
($link0);

?>

So how do you now sort the entire result? It appears you can't use ldap_sort as it uses the search resource which is within the loop.

While another note suggests resetting the control paged result by passing in `0` (zero), it actually still prevents any further queries being ran during the same request.

You actually need to set it to a large number to run further queries it seems. For example:

<?php
ldap_control_paged_result
($connection100true$cookie);

// Run the search
...

// What is supposed to work (reset)
ldap_control_paged_result($connection0false$cookie);

// What actually works
ldap_control_paged_result($connection1000false$cookie);
?>

In the above method, 1000 is just a placeholder, but this seems to actually **limit** further queries to this amount of results, so if you set it to `1`, then you'll only receive **one** result for any further queries during the same request.
