LDAP_OPT_SERVER_CONTROLS and LDAP_OPT_CLIENT_CONTROLS require a list of controls, this means that the value must be an array of controls. A control consists of an oid identifying the control, an optional value, and an optional flag for criticality. In PHP a control is given by an array containing an element with the key oid and string value, and two optional elements. The optional elements are key value with string value and key iscritical with boolean value. iscritical defaults to false if not supplied. See » draft-ietf-ldapext-ldap-c-api-xx.txt for details. See also the second example below.

value

The new value for the specified option.

Return Values

Returns true on success or false on failure.

Changelog

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

Examples

Example #1 Set protocol version


<?php
// $ds is a valid LDAP\Connection instance for a directory server
if (ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) {
    echo "Using LDAPv3";
} else {
    echo "Failed to set protocol version to 3";
}
?>

Example #2 Set server controls


<?php
// $ds is a valid LDAP\Connection instance for a directory server
// control with no value
$ctrl1 = array("oid" => "1.2.752.58.10.1", "iscritical" => true);
// iscritical defaults to FALSE
$ctrl2 = array("oid" => "1.2.752.58.1.10", "value" => "magic");
// try to set both controls
if (!ldap_set_option($ds, LDAP_OPT_SERVER_CONTROLS, array($ctrl1, $ctrl2))) {
    echo "Failed to set server controls";
}
?>
