这个函数很不错，curl函数中的header还可以加入随机UA等功能防屏蔽，以后改改做自己的采集类！

    函数:根据模拟post所得的页面信息，提取所需post的数据和分页，最后分解需要的html
    返回:
        string
/**/
function getHtml(){
    global $html;
    $first = getn();
    preg_match('/(\d+?)<\/b><\/font> 页<\/span>/is', $first, $matches);
    $total = $matches[1];
    preg_match('/
说明：
getHtml是採集入口文件，裏面先取每一頁的數據，並提取頁碼等數據，然後循環採集後面的數據，getn是採集函數，主要是CURL模擬POST了。
