[Rdfapi-php-interest] OntClass

[<sem...@ya...>]

Hello~
 
I'm a beginner for RAP and PHP.
 
I'm trying to get ontClaess by using listClasses()
 
 
$array  = ontModel->listClass();                                     // to get all classes in ontModel
 
foreach( $array as $resource){
 
   $ontClass = (OntClass) $resource;                             // to get OntClass data type
   
   $arrayClass = $ontClass->listSubClasses(true);        // to get sub classes in each class
 
}
 
You know It occurs an error. 
 
Is there anybody to teach me a tip of this problem.
 
 
 
 
Sincerely
 
Antonia
