php菜鸟问题，大家看看

function link($word, $search)
{
  $array = array(
            "baidu" => array(
                          "url" => "http://www.baidu.com/s?wd=link%3A$word",
                          "pattern" => "/页(\d+)/"
                        ),
            "google" => array(
                          "url" => "http://www.google.cn/search?hl=zh-CN&q=link%3A$word&meta=&aq=f",
                          "pattern" => "/约有 <b>(\d+)/"
                        )
  )
    return patternUrl($array[$search]['url'], $array[$search]['pattern']);
}

function patternUrl($url, $pattern)
{
  $html = file_get_contents($url);
  preg_match($pattern,$html, $matches);
  return $matches[1];
}

这个说我  return patternUrl($array[$search]['url'], $array[$search]['pattern']); 
  return 有语法错误  大家看看 小弟菜鸟 帮帮忙
