PHP Manual: Performs an extended operation

Description

mixed ldap_exop(
    LDAP\Connection $ldap,
    string $request_oid,
    string $request_data = null,
    array $controls = null,
    string &$response_data = ?,
    string &$response_oid = ?
)

Performs an extended operation on the specified ldap with request_oid the OID of the operation and request_data the data.

Parameters

ldap: An LDAP\Connection instance, returned by ldap_connect.
request_oid: The extended operation request OID. You may use one of LDAP_EXOP_START_TLS, LDAP_EXOP_MODIFY_PASSWD, LDAP_EXOP_REFRESH, LDAP_EXOP_WHO_AM_I, LDAP_EXOP_TURN, or a string with the OID of the operation you want to send.
request_data: The extended operation request data. May be NULL for some operations like LDAP_EXOP_WHO_AM_I, may also need to be BER encoded.
controls: Array of LDAP Controls to send with the request.
response_data: Will be filled with the extended operation response data if provided. If not provided you may use ldap_parse_exop on the result object later to get this data.
response_oid: Will be filled with the response OID if provided, usually equal to the request OID.

Return Values

When used with response_data, returns true on success or false on error. When used without response_data, returns a result identifier or false on error.

Changelog

Version	Description
8.1.0	The `ldap` parameter expects an LDAP\Connection instance now; previously, a valid `ldap link` resource was expected.
7.3.0	Support for `controls` added

Examples

Example #1 Whoami extended operation

<?php
$ds = ldap_connect("localhost");  // assuming the LDAP server is on this host

if ($ds) {
    // bind with appropriate dn to give update access
    $bind = ldap_bind($ds, "cn=root, o=My Company, c=US", "secret");
    if (!$bind) {
      echo "Unable to bind to LDAP server";
      exit;
    }

    // Call WHOAMI EXOP
    $r = ldap_exop($ds, LDAP_EXOP_WHO_AM_I);

    // Parse the result object
    ldap_parse_exop($ds, $r, $retdata);
    // Output: string(31) "dn:cn=root, o=My Company, c=US"
    var_dump($retdata);

    // Same thing using $response_data parameter
    $success = ldap_exop($ds, LDAP_EXOP_WHO_AM_I, NULL, NULL, $retdata, $retoid);
    if ($success) {
      var_dump($retdata);
    }

    ldap_close($ds);
} else {
    echo "Unable to connect to LDAP server";
}
?>
