What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



hw_getchildcoll — Returns an array of the object IDs of the collection children of an object.


array hw_getchildcoll(hw_link, object_id);
resource hw_link: Connection ID to Hyperwave server
int object_id: Object ID of parent object


Array of object IDs on success; FALSE on failure


hw_getchildcoll() queries the server for any collection children of a given object, returning their object IDs in an array. This function only finds children that are collections; for instance, child documents are not included. If the object identified by object_id has no children that are collections, an empty array is returned.

Example 484. Find child collection object IDs

if (($children = hw_getchildcoll($hw_link, $hyperroot)) !== FALSE) {
    echo "Children collections of the Hyper Root:\n";
} else {
    echo "Could not get children.\n";
