/**
|
|
* Creates XML documents from PHP data structures like arrays, objects or scalars.
|
|
*
|
|
* This class can be used in two modes:
|
|
*
|
|
* 1. Create an XML document from an array or object that is processed by other
|
|
* applications. That means you can create an RDF document from an array in the
|
|
* following format:
|
|
* <code>
|
|
* $data = array(
|
|
* 'channel' => array(
|
|
* 'title' => 'Example RDF channel',
|
|
* 'link' => 'http://www.php-tools.de',
|
|
* 'image' => array(
|
|
* 'title' => 'Example image',
|
|
* 'url' => 'http://www.php-tools.de/image.gif',
|
|
* 'link' => 'http://www.php-tools.de'
|
|
* ),
|
|
* array(
|
|
* 'title' => 'Example item',
|
|
* 'link' => 'http://example.com'
|
|
* ),
|
|
* array(
|
|
* 'title' => 'Another Example item',
|
|
* 'link' => 'http://example.org'
|
|
* )
|
|
* )
|
|
* );
|
|
* </code>
|
|
*
|
|
* To create an RDF document from this array, do the following:
|
|
*
|
|
* <code>
|
|
* require_once 'XML/Serializer.php';
|
|
* $options = array(
|
|
* XML_SERIALIZER_OPTION_INDENT => "\t", // indent with tabs
|
|
* XML_SERIALIZER_OPTION_LINEBREAKS => "\n", // use UNIX line breaks
|
|
* XML_SERIALIZER_OPTION_ROOT_NAME => 'rdf:RDF',// root tag
|
|
* XML_SERIALIZER_OPTION_DEFAULT_TAG => 'item' // tag for values
|
|
* // with numeric keys
|
|
* );
|
|
* $serializer = new XML_Serializer($options);
|
|
* $rdf = $serializer->serialize($data);
|
|
* </code>
|
|
*
|
|
* You will get a complete XML document that can be processed like any RDF document.
|
|
*
|
|
* 2. This class can be used to serialize any data structure in a way that it can
|
|
* later be unserialized again. XML_Serializer will store the type of the value
|
|
* and additional meta information in attributes of the surrounding tag. This
|
|
* meta information can later be used to restore the original data structure
|
|
* in PHP. If you want XML_Serializer to add meta information to the tags, add
|
|
* <code>
|
|
* XML_SERIALIZER_OPTION_TYPEHINTS => true
|
|
* </code>
|
|
* to the options array in the constructor.
