static Literal create(mixed $value, string $lang = null, string $datatype = null)

Create a new literal object

PHP values of type bool, int or float, will automatically be converted to the corresponding datatype and PHP sub-class.

If a registered datatype is given, then the registered subclass of EasyRdf\Literal will instantiated.

Note that literals are not required to have a language or datatype. Literals cannot have both a language and a datatype.

Parameters

mixed $value The value of the literal or an associative array
string $lang The natural language of the literal or null (e.g. 'en')
string $datatype The datatype of the literal or null (e.g. 'xsd:integer')

Return Value

static setDatatypeMapping(string $datatype, string $class)

Register an RDF datatype with a PHP class name

When parsing registered class will be used whenever the datatype is seen.

When serialising a registered class, the mapping will be used to set the datatype in the RDF.

Example: EasyRdf\Literal::registerDatatype('xsd:dateTime', 'My_DateTime_Class');

Parameters

string $datatype The RDF datatype (e.g. xsd:dateTime)
string $class The PHP class name (e.g. My_DateTime_Class)

Exceptions

InvalidArgumentException

static deleteDatatypeMapping(string $datatype)

Remove the mapping between an RDF datatype and a PHP class name

Parameters

string $datatype The RDF datatype (e.g. xsd:dateTime)

Exceptions

Parameters

mixed $value
