# ldap_set_option

(PHP 4 >= 4.0.4, PHP 5)

ldap_set_option -- Set the value of the given option

## Descrição

bool ldap_set_option ( resource link_identifier, int option, mixed newval )

Sets the value of the specified option to be `newval`.

## Parâmetros

`link_identifier`

  An LDAP link identifier, returned by ldap_connect().

`option`

  The parameter `option` can be one of:

  Option | Type |
  `LDAP_OPT_DEREF` | integer |
  `LDAP_OPT_SIZELIMIT` | integer |
  `LDAP_OPT_TIMELIMIT` | 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.

`newval`

  The new value for the specified `option`.

## Valores de retornado

Retorna `TRUE` em caso de sucesso ou `FALSE` em falhas.

## Exemplos

Exemplo 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"; } ?>`

Exemplo 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"; } ?>`
