主要流程就是获取整个网页,然后正则匹配(关键的)。

PHP抓取页面的主要方法,有几种方法是网上前辈的经验,现在还没有用到的,先存下来以后试试。
1.file()函数
2.file_get_contents()函数
3.fopen()->fread()->fclose()模式
4.curl方式 (本人主要用这个)
5.fsockopen()函数 socket模式
6.插件(如:http://sourceforge.net/projects/snoopy/)
7.file()函数
2.使用file_get_contents方法实现,比较简单。
使用file_get_contents和fopen必须空间开启allow_url_fopen。方法:编辑php.ini,设置 allow_url_fopen = On,allow_url_fopen关闭时fopen和file_get_contents都不能打开远程文件。
$url="[http://news.sina.com.cn/c/nd/2016-10-23/doc-ifxwztru6951143.shtml](http://news.sina.com.cn/c/nd/2016-10-23/doc-ifxwztru6951143.shtml)";
$html=file_get_contents($url);
//如果出现中文乱码使用下面代码`
//$getcontent = iconv("gb2312", "utf-8",$html);
echo"";3.fopen()->fread()->fclose()模式 ,目前还没用过,看到了就先记下了
4.使用curl实现(本人一般使用这个)。
使用curl必须空间开启curl。方法:windows下修改php.ini,将extension=php_curl.dll前面的分号去掉,而且需 要拷贝ssleay32.dll和libeay32.dll到C:\\WINDOWS\\system32下;Linux下要安装curl扩展。
(.*?)<\\/script>/',$res,$arr_all);//这个网页中数据通过js包过来,所以直接抓js就可以
preg_match_all('/"id"\\:"(.*?)",/',$arr_all[1][1],$arr1);//从js块中匹配要的数据
$list = array_unique($arr1[1]);//(可省)保证不重复
//以下则是同理,循环则可
for($i=0;$i<=6;$i=$i+2){
$detail_url = 'ht*****em/'.$list[$i];
$detail_res = curl_get_contents($detail_url);
preg_match_all('/
