) : LDAP\Result|array|false
Performs the search for a specified filter on the
directory with the scope LDAP_SCOPE_ONELEVEL.
LDAP_SCOPE_ONELEVEL means that the search should only
return information that is at the level immediately below the
base given in the call.
(Equivalent to typing "ls" and getting a list of files and folders in the
current working directory.)
ldapAn LDAP\Connection instance, returned by ldap_connect().
baseThe base DN for the directory.
filter
attributesAn array of the required attributes, e.g. array("mail", "sn", "cn"). Note that the "dn" is always returned irrespective of which attributes types are requested.
Using this parameter is much more efficient than the default action (which is to return all attributes and their associated values). The use of this parameter should therefore be considered good practice.
attributes_onlyShould be set to 1 if only attribute types are wanted. If set to 0 both attributes types and attribute values are fetched which is the default behaviour.
sizelimitEnables you to limit the count of entries fetched. Setting this to 0 means no limit.
Note:
This parameter can NOT override server-side preset sizelimit. You can set it lower though.
Some directory server hosts will be configured to return no more than a preset number of entries. If this occurs, the server will indicate that it has only returned a partial results set. This also occurs if you use this parameter to limit the count of fetched entries.
timelimitSets the number of seconds how long is spend on the search. Setting this to 0 means no limit.
Note:
This parameter can NOT override server-side preset timelimit. You can set it lower though.
derefSpecifies how aliases should be handled during the search. It can be one of the following:
LDAP_DEREF_NEVER - (default) aliases are never
dereferenced.
LDAP_DEREF_SEARCHING - aliases should be
dereferenced during the search but not when locating the base object
of the search.
LDAP_DEREF_FINDING - aliases should be
dereferenced when locating the base object but not during the search.
LDAP_DEREF_ALWAYS - aliases should be dereferenced
always.
controlsArray of LDAP Controls to send with the request.
Returns an LDAP\Result instance, 或者在失败时返回 false.

Example #1 Produce a list of all organizational units of an organization
<?php
// $ds is a valid link identifier for a directory server
$basedn = "o=My Company, c=US";
$justthese = array("ou");
$sr = ldap_list($ds, $basedn, "ou=*", $justthese);
$info = ldap_get_entries($ds, $sr);
for ($i=0; $i < $info["count"]; $i++) {
echo $info[$i]["ou"][0];
}
?>
