Usage example
=============

[](#usage-example)

```
use alcamo\rdf_literal\LiteralFactory;

include $_composer_autoload_path ?? __DIR__ . '/../vendor/autoload.php';

$factory = new LiteralFactory();

$number = $factory->create(1970);

echo $number . PHP_EOL;

echo $number->getDatatypeUri() . PHP_EOL;

$year = $factory->create(1970, LiteralFactory::XSD_NS . 'gYear');

echo $year . PHP_EOL;

echo $year->getDatatypeUri() . PHP_EOL;

echo "Literals are "
    . ($year->equals($number) ? '' : 'not')
    . ' equal' . PHP_EOL;

```

This example is contained in this package as a file in the `bin`directory. It will output

```
1970
http://www.w3.org/2001/XMLSchema#integer
1970
http://www.w3.org/2001/XMLSchema#gYear
Literals are not equal

```

Overview
========

[](#overview)

The classes that implement `LiteralInterface` represent the concept of [RDF Literals](https://www.w3.org/TR/2014/REC-rdf11-concepts-20140225/#section-Graph-Literal), i.e. data elements that have a datataype and may have a language tag.

Among others, this allows to:

- Create values of various types from strings, governed by an XSD datatype URI.
- Add a \_\_toString() function to values which are not stringable.
- Add a custom \_\_toString() function which differs from the default representation of a value.
- Distinguish values that may be represented the same way in PHP but have different meanings.

See the doxygen documentation for details.
