Description

hw_children() is used to get object identifiers for all of the children of an object. hw_link is the connection ID to the server on which the object resides, and object_id is the ID of the object whose children you want to obtain.

The child IDs are returned in an array; all children (collections and documents) of the given object are returned. If you want to retrieve only child collections, use hw_getchildcoll() ; if you want to retrieve only child documents, use hw_getchilddoccoll() .

$hyperroot = hw_root();
if (($children = hw_children($hw_link, $hyperroot)) !== FALSE) {
    echo "Children of the Hyper Root:\n";
    print_r($children);
} else {
    echo "Could not get children.<br/>\n";
}
