我是一个新手，想使用php抓取微信页面的正文和标题，标题直接用正则表达式|<title>(.*?)<\/title>|i就抓取到了，但是正文我想的是|>(.*?)<\/|i匹配标签间的内容，再去掉空格，但是还是会匹配到一堆标签，是怎么回事？或者说有其他更好的方法吗？求指教！

随便折腾～见笑
这种问题，放弃用正则吧，要真正完备的你可能得写一篇文章那样长。但 html 已经是结构化的了，找个 html 解析库就行了，我刚用 firebug 粗略的看了下，正文是在 id 为 page-content 的 p 里。
当然，如果我所看到的是受 js 影响后的页面状态，那你可能得挂个浏览器内核来帮你获取到最终页面状态了。幸好，这个有很多开源的。
可以尝试使用DOM操作库simple-html-dom.php,快速获取HTML结构的内容:
可以把抓取到的内容写入置于内存上的SQLite(/run/shm/php/crawler.db3),避免频繁的磁盘IO.
把文章页面代码贴上来。
曾经尝试爬取微信文章，结果被黑警告 = =
没必要用正则表达式的，可以用PHP像jQuery那样直接操作DOM的，你可以参考一下。 http://www.cnphp.info/php-simple-html-dom-parser-intro.html
我之前使用的phpquery去抓的微信文章,从搜狗进去的,但是不能太频繁,我是把列表抓下来,存入数据库,然后用计划任务60秒抓一次详情,这里的详情注意里面的html解析,我记得视频地址跟图片解析是要注意下的,
建议使用selenium工具通过浏览器渲染获取到加载完成后的界面，然后通过界面解析获取想要的内容~
看到一个爬微信的站http://dedecms5.com
是用工具库
phpquery
类似jQuery的方式解析html
用来抓站什么的很方便
