Snoopy class, methods:

fetch($URI)

Method used to crawl the content of web pages. The $URI parameter is the URL address of the crawled web page. The fetched results are stored in $this->results. If you are scraping a frame, Snoopy will track each frame and store it in an array, then store it in $this->results.

fetchtext($URI)

This method is similar to fetch(). The only difference is that this method will remove HTML tags and other irrelevant data, and only return the text content in the web page.

fetchform($URI)

This method is similar to fetch(). The only difference is that this method will remove HTML tags and other irrelevant data, and only return the form content (form) in the web page.

fetchlinks($URI)

This method is similar to fetch(). The only difference is that this method will remove HTML tags and other irrelevant data, and only return links in the web page. By default, relative links will be automatically completed and converted into full URLs.

submit($URI,$formvars)

This method sends a confirmation form to the link address specified by $URL. $formvars is an array that stores form parameters.

submittext($URI,$formvars)

This method is similar to submit(). The only difference is that this method will remove HTML tags and other irrelevant data, and only return the text content of the web page after login.

submitlinks($URI)

This method is similar to submit(). The only difference is that this method will remove HTML tags and other irrelevant data, and only return the link in the web page. By default, relative links will be automatically completed and converted into full URLs.
