$query = "SELECT * FROM `#@__archives` WHERE `typeid` = 1";
$dsql->SetQuery($query);
$dsql->Execute();

while($row = $dsql->GetArray()){
    $body = $row['body'];
    
    // 进行替换操作
    $newBody = str_replace($search, $replace, $body);
    
    // 更新文章内容
    $updateSql = "UPDATE `#@__archives` SET `body`='{$newBody}' WHERE `id`={$row['id']}";
