-/**
-* 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.

-/**
-* LDIF capabilitys for Net_LDAP2, closely taken from PERLs Net::LDAP
-*
-* It provides a means to convert between Net_LDAP2_Entry objects and LDAP entries
-* represented in LDIF format files. Reading and writing are supported and may
-* manipulate single entries or lists of entries.
-*
-* Usage example:
-* <code>
-* // Read and parse an ldif-file into Net_LDAP2_Entry objects
-* // and print out the DNs. Store the entries for later use.
-* require 'Net/LDAP2/LDIF.php';
-* $options = array(
-* 'onerror' => 'die'
-* );
-* $entries = array();
-* $ldif = new Net_LDAP2_LDIF('test.ldif', 'r', $options);
-* do {
-* $entry = $ldif->read_entry();
-* $dn = $entry->dn();
-* echo " done building entry: $dn\n";
-* array_push($entries, $entry);
-* } while (!$ldif->eof());
-* $ldif->done();
-*
-*
-* // write those entries to another file
-* $ldif = new Net_LDAP2_LDIF('test.out.ldif', 'w', $options);
-* $ldif->write_entry($entries);
-* $ldif->done();

- *
- * OPTIONS is an associative array and may contain:
- * encode => 'none' | 'canonical' | 'base64'
- * Some DN values in LDIF cannot be written verbatim and have to be encoded in some way:
- * 'none' No encoding.
- * 'canonical' See "canonical_dn()" in Net::LDAP::Util.
- * 'base64' Use base64. (default, this differs from the Perl interface.
- * The perl default is "none"!)
- *
- * onerror => 'die' | 'warn' | NULL
- * Specify what happens when an error is detected.
- * 'die' Net_LDAP2_LDIF will croak with an appropriate message.
- * 'warn' Net_LDAP2_LDIF will warn (echo) with an appropriate message.
- * NULL Net_LDAP2_LDIF will not warn (default), use error().
- *
- * change => 1
- * Write entry changes to the LDIF file instead of the entries itself. I.e. write LDAP
- * operations acting on the entries to the file instead of the entries contents.
- * This writes the changes usually carried out by an update() to the LDIF file.
- *
- * lowercase => 1
- * Convert attribute names to lowercase when writing.
- *
- * sort => 1
- * Sort attribute names when writing entries according to the rule:
- * objectclass first then all other attributes alphabetically sorted by attribute name
- *
- * version => '1'
- * Set the LDIF version to write to the resulting LDIF file.
- * According to RFC 2849 currently the only legal value for this option is 1.
- * When this option is set Net_LDAP2_LDIF tries to adhere more strictly to
- * the LDIF specification in RFC2489 in a few places.
- * The default is NULL meaning no version information is written to the LDIF file.
- *
- * wrap => 78
- * Number of columns where output line wrapping shall occur.
- * Default is 78. Setting it to 40 or lower inhibits wrapping.
- *
- * raw => REGEX
- * Use REGEX to denote the names of attributes that are to be
- * considered binary in search results if writing entries.
- * Example: raw => "/(?i:^jpegPhoto|;binary)/i"

- * 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')

- * Split an multivalued RDN value into an Array
- *
- * A RDN can contain multiple values, spearated by a plus sign.
- * 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.
- *
- * For example, the multivalued RDN 'OU=Sales+CN=J. Smith' is exploded to:
- * <kbd>array([0] => 'OU=Sales', [1] => 'CN=J. Smith')</kbd>
- *
- * The method trys to be smart if it encounters unescaped "+" characters, but may fail,
- * so ensure escaped "+"es in attr names and attr values.
- *
- * [BUG] If you have a multivalued RDN with unescaped plus characters
- * and there is a unescaped plus sign at the end of an value followed by an
- * attribute name containing an unescaped plus, then you will get wrong splitting:
- * $rdn = 'OU=Sales+C+N=J. Smith';
- * 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.
- *
- * @param string $rdn Part of an (multivalued) escaped RDN (eg. ou=foo OR ou=foo+cn=bar)
- *
- * @static
- * @return array Array with the components of the multivalued RDN or Error
