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



hw_setlinkroot — Sets an object as the root by which links are calculated.


int hw_setlinkroot(hw_link, root_id);
resource hw_link: Connection ID to Hyperwave server
int root_id: Object ID of object to use as the root


Object ID of the new root on success; FALSE on failure


hw_setlinkroot() allows you to change the object used by Hyperwave to calculate relative links. The object ID given by root_id is used for future relative link derivation.


PHP 3 since 3.0.3, PHP 4


Example 523. Set a new link root

if (hw_setlinkroot($hw_link, $new_root) != $new_root) {
    echo "Could not set new link root; reason: " . hw_errormsg($hw_link) . ".\n";
} else {
    echo "The link root is now $new_root.\n";
