NAME

       PHP::Serialization - simple flexible means of converting the output of PHP's serialize() into the equivalent Perl memory structure, and
       vice versa.

SYNOPSIS

	   use PHP::Serialization qw(serialize unserialize);
	   my $encoded = serialize({ a => 1, b => 2});
	   my $hashref = unserialize($encoded);

DESCRIPTION

       Provides a simple, quick means of serializing perl memory structures (including object data!) into a format that PHP can deserialize() and
       access, and vice versa.

       NOTE: Converts PHP arrays into Perl Arrays when the PHP array used exclusively numeric indexes, and into Perl Hashes then the PHP array did
       not.

FUNCTIONS

       Exportable functions..

   serialize($var,[optional $asString,[optional $sortHashes]])
       Serializes the memory structure pointed to by $var, and returns a scalar value of encoded data.

       If the optional $asString is true, $var will be encoded as string if it is double or float.

       If the optional $sortHashes is true, all hashes will be sorted before serialization.

       NOTE: Will recursively encode objects, hashes, arrays, etc.

       SEE ALSO: ->encode()

   unserialize($encoded,[optional CLASS])
       Deserializes the encoded data in $encoded, and returns a value (be it a hashref, arrayref, scalar, etc) representing the data structure
       serialized in $encoded_string.

       If the optional CLASS is specified, any objects are blessed into CLASS::$serialized_class. Otherwise, O bjects are blessed into
       PHP::Serialization::Object::$serialized_class. (which has no methods)

       SEE ALSO: ->decode()

METHODS

       Functionality available if using the object interface..

   decode($encoded_string,[optional CLASS])
       Deserializes the encoded data in $encoded, and returns a value (be it a hashref, arrayref, scalar, etc) representing the data structure
       serialized in $encoded_string.

       If the optional CLASS is specified, any objects are blessed into CLASS::$serialized_class. Otherwise, Objects are blessed into
       PHP::Serialization::Object::$serialized_class. (which has no methods)

       SEE ALSO: unserialize()

   encode($reference,[optional $asString,[optional $sortHashes]])
       Serializes the memory structure pointed to by $reference, and returns a scalar value of encoded data.

       If the optional $asString is true, $reference will be encoded as string if it is double or float.

       If the optional $sortHashes is true, all hashes will be sorted before serialization.

       NOTE: Will recursively encode objects, hashes, arrays, etc.

       SEE ALSO: serialize()

TODO

       Support diffrent object types

Net::DNS::DomainName(3) 				User Contributed Perl Documentation				   Net::DNS::DomainName(3)

NAME

       Net::DNS::DomainName - DNS domain name wire representation

SYNOPSIS

	   use Net::DNS::DomainName;

	   $object = new Net::DNS::DomainName('example.com');
	   $name = $object->name;
	   $data = $object->encode;

	   ( $object, $next ) = decode Net::DNS::DomainName( $data, $offset );

DESCRIPTION

       The Net::DNS::DomainName module implements the concrete representation of DNS domain names used within DNS packets.

       Net::DNS::DomainName defines methods for encoding and decoding wire format octet strings as defined in RFC1035. All other behaviour,
       including the new() constructor, is inherited from Net::DNS::Domain.

       The Net::DNS::DomainName1035 and Net::DNS::DomainName2535 packages implement disjoint domain name subtypes which provide the name
       compression and canonicalisation specified by RFC1035 and RFC2535.  These are necessary to meet the backward compatibility requirements
       introduced by RFC3597.

METHODS

   new
	   $object = new Net::DNS::DomainName('example.com');

       Creates a domain name object which identifies the domain specified by the character string argument.

   decode
	   $object = decode Net::DNS::DomainName( $buffer, $offset, $hash );

	   ( $object, $next ) = decode Net::DNS::DomainName( $buffer, $offset, $hash );

       Creates a domain name object which represents the DNS domain name identified by the wire-format data at the indicated offset within the
       data buffer.

       The argument list consists of a reference to a scalar containing the wire-format data and specified offset. The optional reference to a
       hash table provides improved efficiency of decoding compressed names by exploiting already cached compression pointers.

       The returned offset value indicates the start of the next item in the data buffer.

   encode
	   $data = $object->encode;

       Returns the wire-format representation of the domain name suitable for inclusion in a DNS packet buffer.

Net::DNS::DomainName1035
       Net::DNS::DomainName1035 implements a subclass of domain name objects which are to be encoded using the compressed wire format defined in
       RFC1035.

	   use Net::DNS::DomainName;

	   $object = new Net::DNS::DomainName1035('compressible.example.com');
	   $data   = $object->encode( $offset, $hash );

	   ( $object, $next ) = decode Net::DNS::DomainName1035( $data, $offset );

       Note that RFC3597 implies that the RR types defined in RFC1035 section 3.3 are the only types eligible for compression.

   encode
	   $data = $object->encode( $offset, $hash );

       Returns the wire-format representation of the domain name suitable for inclusion in a DNS packet buffer.

       The optional arguments are the offset within the packet data where the domain name is to be stored and a reference to a hash table used to
       index compressed names within the packet.

       If the hash reference is undefined, encode() returns the lowercase uncompressed canonical representation defined in RFC2535(8.1).

Net::DNS::DomainName2535
       Net::DNS::DomainName2535 implements a subclass of domain name objects which are to be encoded using uncompressed wire format.

       Note that RFC3597, and latterly RFC4034, specifies that the lower case canonical encoding defined in RFC2535 is to be used for RR types
       defined prior to RFC3597.

	   use Net::DNS::DomainName;

	   $object = new Net::DNS::DomainName2535('incompressible.example.com');
	   $data   = $object->encode( $offset, $hash );

	   ( $object, $next ) = decode Net::DNS::DomainName2535( $data, $offset );

   encode
	   $data = $object->encode( $offset, $hash );

       Returns the uncompressed wire-format representation of the domain name suitable for inclusion in a DNS packet buffer.

       If the hash reference is undefined, encode() returns the lowercase canonical form defined in RFC2535(8.1).
