Example #1 LDAP pagination

 <?php
     // $ds is a valid link identifier (see ldap_connect)
     ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

     $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($ds, 1);

     $sr = ldap_search($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.

 <?php
     // $ds is a valid link identifier (see ldap_connect)
     ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

     $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, $pageSize, true, $cookie);

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