可否帮忙写一个单页页的PHP采集程序,并附上实例
比方说,我要采集这个页面:http://news.163.com/12/0613/20/83TJ7PA700014JB6.html
要求:
采集标题
采集正文
谢谢!

首先去http://simplehtmldom.sourceforge.net/index.htm(点击Download latest version form Sourceforge.)下载一个simple_html_dom.php,傻瓜式的正则,另官网上有详细教程,很容易看懂。
<br /> header("Content-type: text/html; charset=gb2312");<br /> require dirname(__FILE__) . '/simple_html_dom.php';<br /> $ch = curl_init();<br /> curl_setopt($ch, CURLOPT_URL, 'http://news.163.com/12/0613/20/83TJ7PA700014JB6.html');<br /> curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);<br /> curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 GTB5');<br /> $htmls = curl_exec($ch);<br /> curl_close($ch);<br /> $html = str_get_html($htmls);<br /> foreach($html->find('#h1title') as $title){ <br /> echo strip_tags($title).'<br />';//标题<br /> }<br /> foreach($html->find('#endText') as $content){ <br /> echo strip_tags($content);//正文<br /> }
注:curl模拟Mozilla浏览器抓取,比file_get_contents()解析速度更快。strip_tags() 用以去除那个邪恶的iframe广告,反正你需要的是“采集标题”和“采集正文”冗余的html标签对你无用。

本文为大家介绍有关如何运用PHP获取QQ邮箱好友的方法。PHP有一个扩展是curl扩展,该扩展一般用于采集数据。但是也可以实现模拟登陆,通过模拟登陆来登陆QQ邮箱,再利用curl的采集来获取邮箱的好友列表。以上是实现原理,理解袁莉以后我们来看实现过程。具体的PHP获取QQ邮箱好友的代码如下:
1. 2.class QQHttp {
3. var $cookie = '';
4. function __cunstrut() {
5. }
6. function makeForm() {
7. $form = array(
8. 'url' => "http://mail.qq.com/cgi-bin/loginpage",
9. );
10. $data = $this->curlFunc($form);
11. preg_match('/name="ts"svalue="(d+)"/',$data['html'], $tspre);
12. $ts = $tspre[1];
13. preg_match('/action="http://(md+).mail.qq.com/',$data['html'], $server);
14. $server_no = $server[1];
15. /* login.html 载入 */
16. $html = file_get_contents(dirname(__FILE__).'/login.htm');
17. $html = str_replace('{_ts_}',$ts, $html);
18. $html = str_replace('{_server_no_}',$server_no, $html);
19. return $html;
20. }
21. function curlFunc($array)
22. {
23. $ch = curl_init();
24. curl_setopt($ch, CURLOPT_URL, $array['url']);

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
