Search data

Further, it is possible to search statements in the model. The search function contains three parameters, namely, subject, predicate and object, and returns an array containing all results. If a parameters is defined as NULL, it can be seen as a placeholder and is true for all statements in the model. Since we want to enable users to further use the resource-centric approach we added two search functions. The function $result = $model->search($subject, $predicate, $object) merely returns a list of statements, while the function $result = $model->searchResources($subject, $predicate, $object) returns a list of resources with properties. Usage of the search functions is presented in code snippet 5.4.

<?php
	require_once 'path/to/API.php';
       
        // create or load model
        // create the $subject, $predicate, $object

        // returns list of statements
        $result = $model->search($subject, $predicate, $object);
        
        // returns list of resources + properties
        $result = $model->searchResources($subject, $predicate, $object);
?>
