Zend_Ldap is the base interface into a LDAP server. It provides connection and binding methods as well as methods to operate on the LDAP tree. Method Description string filterEscape(string $str) Escapes a value to be used in a LDAP filter according to RFC 2254. This method is deprecated, please use Zend_Ldap_Filter_Abstract::escapeValue() instead. boolean explodeDn($dn, array &$keys = null, array &$vals = null) Checks if a given DN $dn is malformed. If $keys or $keys and $vals are given, these arrays will be filled with the appropriate DN keys and values. This method is deprecated, please use Zend_Ldap_Dn::checkDn() instead. __construct($options) Constructor. The $options parameter is optional and can be set to an array or a Zend_Config instance. If no options are provided at instantiation, the connection parameters must be passed to the instance using Zend_Ldap::setOptions(). The allowed options are specified in Zend_Ldap Options resource getResource() Returns the raw LDAP extension (ext/ldap) resource. integer getLastErrorCode() Returns the LDAP error number of the last LDAP command. string getLastError(integer &$errorCode, array &$errorMessages) Returns the LDAP error message of the last LDAP command. The optional $errorCode parameter is set to the LDAP error number when given. The optional $errorMessages array will be filled with the raw error messages when given. The various LDAP error retrieval functions can return different things, so they are all collected if $errorMessages is given. Zend_Ldap setOptions($options) Sets the LDAP connection and binding parameters. $options can be an array or an instance of Zend_Config. The allowed options are specified in Zend_Ldap Options array getOptions() Returns the current connection and binding parameters. string getBaseDn() Returns the base DN this LDAP connection is bound to. string getCanonicalAccountName(string $acctname, integer $form) Returns the canonical account name of the given account name $acctname. $form specifies the format into which the account name is canonicalized. See Account Name Canonicalization for more details. Zend_Ldap disconnect() Disconnects the Zend_Ldap instance from the LDAP server. Zend_Ldap connect(string $host, integer $port, boolean $useSsl, boolean $useStartTls) Connects the Zend_Ldap instance to the given LDAP server. All parameters are optional and will be taken from the LDAP connection and binding parameters passed to the instance via the construtor or via Zend_Ldap::setOptions() when set to NULL. Zend_Ldap bind(string $username, string $password) Authenticates $username with $password at the LDAP server. If both paramaters are omitted the binding will be carried out with the credentials given in the connection and binding parameters. If no credentials are given in the connection and binding parameters an anonymous bind will be performed. Note that this requires anonymous binds to be allowed on the LDAP server. An empty string '' can be passed as $password together with a username if, and only if, allowEmptyPassword is set to TRUE in the connection and binding parameters. Zend_Ldap_Collection search(string|Zend_Ldap_Filter_Abstract $filter, string|Zend_Ldap_Dn $basedn, integer $scope, array $attributes, string $sort, string $collectionClass) Searches the LDAP tree with the given $filter and the given search parameters. string|Zend_Ldap_Filter_Abstract $filter The filter string to be used in the search, e.g. (objectClass=posixAccount). string|Zend_Ldap_Dn $basedn The search base for the search. If omitted or NULL, the baseDn from the connection and binding parameters is used. integer $scope The search scope. Zend_Ldap::SEARCH_SCOPE_SUB searches the complete subtree including the $baseDn node. Zend_Ldap::SEARCH_SCOPE_ONE restricts search to one level below $baseDn. Zend_Ldap::SEARCH_SCOPE_BASE restricts search to the $baseDn itself; this can be used to efficiently retrieve a single entry by its DN. The default value is Zend_Ldap::SEARCH_SCOPE_SUB. array $attributes Specifies the attributes contained in the returned entries. To include all possible attributes (ACL restrictions can disallow certain attribute to be retrieved by a given user) pass either an empty array array() or array('*') to the method. On some LDAP servers you can retrieve special internal attributes by passing array('*', '+') to the method. string $sort If given the result collection will be sorted after the attribute $sort. Results can only be sorted after one single attribute as this parameter uses the ext/ldap function ldap_sort(). string $collectionClass If given the result will be wrapped in an object of type $collectionClass. By default an object of type Zend_Ldap_Collection will be returned. The custom class must extend Zend_Ldap_Collection and will be passed a Zend_Ldap_Collection_Iterator_Default on instantiation. integer count(string|Zend_Ldap_Filter_Abstract $filter, string|Zend_Ldap_Dn $basedn, integer $scope) Counts the elements returned by the given search parameters. See Zend_Ldap::search() for a detailed description of the method parameters. integer countChildren(string|Zend_Ldap_Dn $dn) Counts the direct descendants (children) of the entry identified by the given $dn. boolean exists(string|Zend_Ldap_Dn $dn) Checks whether the entry identified by the given $dn exists. array searchEntries(string|Zend_Ldap_Filter_Abstract $filter, string|Zend_Ldap_Dn $basedn, integer $scope, array $attributes, string $sort) Performs a search operation and returns the result as an PHP array. This is essentially the same method as Zend_Ldap::search() except for the return type. See Zend_Ldap::search() for a detailed description of the method parameters. array getEntry(string|Zend_Ldap_Dn $dn, array $attributes, boolean $throwOnNotFound) Retrieves the LDAP entry identified by $dn with the attributes specified in $attributes. If $attributes is ommitted, all attributes (array()) are included in the result. $throwOnNotFound is FALSE by default, so the method will return NULL if the specified entry cannot be found. If set to TRUE, a Zend_Ldap_Exception will be thrown instead. void prepareLdapEntryArray(array &$entry) Prepare an array for the use in LDAP modification operations. This method does not need to be called by the end-user as it's implicitly called on every data modification method. Zend_Ldap add(string|Zend_Ldap_Dn $dn, array $entry) Adds the entry identified by $dn with its attributes $entry to the LDAP tree. Throws a Zend_Ldap_Exception if the entry could not be added. Zend_Ldap update(string|Zend_Ldap_Dn $dn, array $entry) Updates the entry identified by $dn with its attributes $entry to the LDAP tree. Throws a Zend_Ldap_Exception if the entry could not be modified. Zend_Ldap save(string|Zend_Ldap_Dn $dn, array $entry) Saves the entry identified by $dn with its attributes $entry to the LDAP tree. Throws a Zend_Ldap_Exception if the entry could not be saved. This method decides by querying the LDAP tree if the entry will be added or updated. Zend_Ldap delete(string|Zend_Ldap_Dn $dn, boolean $recursively) Deletes the entry identified by $dn from the LDAP tree. Throws a Zend_Ldap_Exception if the entry could not be deleted. $recursively is FALSE by default. If set to TRUE the deletion will be carried out recursively and will effectively delete a complete subtree. Deletion will fail if $recursively is FALSE and the entry $dn is not a leaf entry. Zend_Ldap moveToSubtree(string|Zend_Ldap_Dn $from, string|Zend_Ldap_Dn $to, boolean $recursively, boolean $alwaysEmulate) Moves the entry identified by $from to a location below $to keeping its RDN unchanged. $recursively specifies if the operation will be carried out recursively (FALSE by default) so that the entry $from and all its descendants will be moved. Moving will fail if $recursively is FALSE and the entry $from is not a leaf entry. $alwaysEmulate controls whether the ext/ldap function ldap_rename() should be used if available. This can only work for leaf entries and for servers and for ext/ldap supporting this function. Set to TRUE to always use an emulated rename operation. All move-operations are carried out by copying and then deleting the corresponding entries in the LDAP tree. These operations are not atomic so that failures during the operation will result in an inconsistent state on the LDAP server. The same is true for all recursive operations. They also are by no means atomic. Please keep this in mind. Zend_Ldap move(string|Zend_Ldap_Dn $from, string|Zend_Ldap_Dn $to, boolean $recursively, boolean $alwaysEmulate) This is an alias for Zend_Ldap::rename(). Zend_Ldap rename(string|Zend_Ldap_Dn $from, string|Zend_Ldap_Dn $to, boolean $recursively, boolean $alwaysEmulate) Renames the entry identified by $from to $to. $recursively specifies if the operation will be carried out recursively (FALSE by default) so that the entry $from and all its descendants will be moved. Moving will fail if $recursively is FALSE and the entry $from is not a leaf entry. $alwaysEmulate controls whether the ext/ldap function ldap_rename() should be used if available. This can only work for leaf entries and for servers and for ext/ldap supporting this function. Set to TRUE to always use an emulated rename operation. Zend_Ldap copyToSubtree(string|Zend_Ldap_Dn $from, string|Zend_Ldap_Dn $to, boolean $recursively) Copies the entry identified by $from to a location below $to keeping its RDN unchanged. $recursively specifies if the operation will be carried out recursively (FALSE by default) so that the entry $from and all its descendants will be copied. Copying will fail if $recursively is FALSE and the entry $from is not a leaf entry. Zend_Ldap copy(string|Zend_Ldap_Dn $from, string|Zend_Ldap_Dn $to, boolean $recursively) Copies the entry identified by $from to $to. $recursively specifies if the operation will be carried out recursively (FALSE by default) so that the entry $from and all its descendants will be copied. Copying will fail if $recursively is FALSE and the entry $from is not a leaf entry. Zend_Ldap_Node getNode(string|Zend_Ldap_Dn $dn) Returns the entry $dn wrapped in a Zend_Ldap_Node. Zend_Ldap_Node getBaseNode() Returns the entry for the base DN $baseDn wrapped in a Zend_Ldap_Node. Zend_Ldap_Node_RootDse getRootDse() Returns the RootDSE for the current server. Zend_Ldap_Node_Schema getSchema() Returns the LDAP schema for the current server. Zend_Ldap_Collection implements Iterator to allow for item traversal using foreach() and Countable to be able to respond to count(). With its protected _createEntry() method it provides a simple extension point for developers needing custom result objects. Method Description __construct(Zend_Ldap_Collection_Iterator_Interface $iterator) Constructor. The constrcutor must be provided by a Zend_Ldap_Collection_Iterator_Interface which does the real result iteration. Zend_Ldap_Collection_Iterator_Default is the default implementation for iterating ext/ldap results. boolean close() Closes the internal iterator. This is also called in the destructor. array toArray() Returns all entries as an array. array getFirst() Returns the first entry in the collection or NULL if the collection is empty.
