: Http://sourceforge.net/projects/snoopy/
Some features of Snoopy:
1. Fetch the webpage content
2. fetchtext
3. Capture the link of the web page, form fetchlinks fetchform
4. Support for proxy hosts
5. basic user name/password verification is supported.
6. You can set user_agent, Referer, cookies, and header content)
7. Supports browser redirection and can control the depth of redirection.
8. Extend the link in the webpage to a high-quality URL (default)
9. submit data and obtain the returned value
10. Support tracking HTML framework
11. Transfer cookies when redirection is supported
You only need PhP4 and above. Because it is a PHP class, you do not need to expand the support. The best choice is when the server does not support curl.

Class method:

Fetch ($ URI)
----
This method is used to capture the content of a webpage.
$ URI is the URL of the webpage to be crawled.
The captured results are stored in $ this-> results.
If you are capturing a framework, Snoopy will track each frame and store it in an array, and then save it to $ this-> results.

Fetchtext ($ URI)

Fetchlinks ($ URI)
