Loads a record from the database. If an error occurs it returns false, otherwise true. If the optional 3rd parameter $lock is set to true, the database lock statement is applied to the SELECTed records.

$person = new person();
$person->Load("id=1");
foreach($person->children as $c)
{
    echo " $c->name_first ";
    $c->name_first .= ' K.';
    $c->Save();  ## each child record must be saved individually
}
