ldap_set_option — Set the value of the given option
Sets the value of the specified option to be newval .
An LDAP link identifier, returned by ldap_connect().
The parameter option can be one of:
| Option | Type |
|---|---|
| LDAP_OPT_DEREF | integer |
| LDAP_OPT_SIZELIMIT | integer |
| LDAP_OPT_TIMELIMIT | integer |
| LDAP_OPT_NETWORK_TIMEOUT | integer |
| LDAP_OPT_PROTOCOL_VERSION | integer |
| LDAP_OPT_ERROR_NUMBER | integer |
| LDAP_OPT_REFERRALS | bool |
| LDAP_OPT_RESTART | bool |
| LDAP_OPT_HOST_NAME | string |
| LDAP_OPT_ERROR_STRING | string |
| LDAP_OPT_MATCHED_DN | string |
| LDAP_OPT_SERVER_CONTROLS | array |
| LDAP_OPT_CLIENT_CONTROLS | array |
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.
The new value for the specified option .
如果成功则返回 TRUE，失败则返回 FALSE。
Example #1 Set protocol version
<?php
// $ds is a valid link identifier for a directory server
if (ldap_set_option($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 link identifier 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";
}
?>
