/**
|
||||
* Object representation of a part of a LDAP filter.
|
||||
*
|
||||
* This Class is not completely compatible to the PERL interface!
|
||||
*
|
||||
* The purpose of this class is, that users can easily build LDAP filters
|
||||
* without having to worry about right escaping etc.
|
||||
* A Filter is built using several independent filter objects
|
||||
* which are combined afterwards. This object works in two
|
||||
* modes, depending how the object is created.
|
||||
* If the object is created using the {@link create()} method, then this is a leaf-object.
|
||||
* If the object is created using the {@link combine()} method, then this is a container object.
|
||||
*
|
||||
* LDAP filters are defined in RFC-2254 and can be found under
|
||||
* {@link http://www.ietf.org/rfc/rfc2254.txt}
|
||||
*
|
||||
* Here a quick copy&paste example:
|
||||
* <code>
|
||||
* $filter0 = Net_LDAP2_Filter::create('stars', 'equals', '***');
|
||||
* $filter_not0 = Net_LDAP2_Filter::combine('not', $filter0);
|
||||
*
|
||||
* $filter1 = Net_LDAP2_Filter::create('gn', 'begins', 'bar');
|
||||
* $filter2 = Net_LDAP2_Filter::create('gn', 'ends', 'baz');
|
||||
* $filter_comp = Net_LDAP2_Filter::combine('or',array($filter_not0, $filter1, $filter2));
|
||||
*
|
||||
* echo $filter_comp->asString();
|
||||
* // This will output: (|(!(stars=\0x5c0x2a\0x5c0x2a\0x5c0x2a))(gn=bar*)(gn=*baz))
|
||||
* // The stars in $filter0 are treaten as real stars unless you disable escaping.

|

* Explodes the given DN into its elements
|

*
|
||||
* {@link http://www.ietf.org/rfc/rfc2253.txt RFC 2253} says, a Distinguished Name is a sequence
|
||||
* of Relative Distinguished Names (RDNs), which themselves
|
||||
* are sets of Attributes. For each RDN a array is constructed where the RDN part is stored.
|
||||
*
|
||||
* For example, the DN 'OU=Sales+CN=J. Smith,DC=example,DC=net' is exploded to:
|
||||
* <kbd>array( [0] => array([0] => 'OU=Sales', [1] => 'CN=J. Smith'), [2] => 'DC=example', [3] => 'DC=net' )</kbd>
|
||||
*
|
||||
* [NOT IMPLEMENTED] DNs might also contain values, which are the bytes of the BER encoding of
|
||||
* the X.500 AttributeValue rather than some LDAP string syntax. These values are hex-encoded
|
||||
* and prefixed with a #. To distinguish such BER values, ldap_explode_dn uses references to
|
||||
* the actual values, e.g. '1.3.6.1.4.1.1466.0=#04024869,DC=example,DC=com' is exploded to:
|
||||
* [ { '1.3.6.1.4.1.1466.0' => "\004\002Hi" }, { 'DC' => 'example' }, { 'DC' => 'com' } ];
|
||||
* See {@link http://www.vijaymukhi.com/vmis/berldap.htm} for more information on BER.
|
||||
*
|
||||
* It also performs the following operations on the given DN:
|
||||
* - Unescape "\" followed by ",", "+", """, "\", "<", ">", ";", "#", "=", " ", or a hexpair
|
||||
* and strings beginning with "#".
|
||||
* - Removes the leading 'OID.' characters if the type is an OID instead of a name.
|
||||
* - If an RDN contains multiple parts, the parts are re-ordered so that the attribute type names are in alphabetical order.
|
||||
*
|
||||
* OPTIONS is a list of name/value pairs, valid options are:
|
||||
* casefold Controls case folding of attribute types names.
|
||||
* Attribute values are not affected by this option.
|
||||
* The default is to uppercase. Valid values are:
|
||||
* lower Lowercase attribute types names.
|
||||
* upper Uppercase attribute type names. This is the default.
|
||||
* none Do not change attribute type names.
|
||||
* reverse If TRUE, the RDN sequence is reversed.
|
||||
* onlyvalues If TRUE, then only attributes values are returned ('foo' instead of 'cn=foo')

* This function returns each separate ocl=value pair of the RDN part.
|

|

* If no multivalued RDN is detected, an array containing only

* the original rdn part is returned.
|

* <kbd>array([0] => 'OU=Sales', [1] => 'CN=J. Smith')</kbd>
|

* so ensure escaped "+"es in attr names and attr values.

* [BUG] If you have a multivalued RDN with unescaped plus characters

* attribute name containing an unescaped plus, then you will get wrong splitting:

* returns:

* array('OU=Sales+C', 'N=J. Smith');

* The "C+" is treaten as value of the first pair instead as attr name of the second pair.
|

* To prevent this, escape correctly.
