问题
I'm doing a PHP project (using Codeigniter) on text summarization and for that I need to extract sentences from content of a Rich TextBox (this content includes tags). Therefore is there a proper method or Codeigniter library to extract sentences from a content containing HTML tags?
回答1:
A php function strip_tags() should help you. It returns string without php and html tags. If you just need to count sentences, you could do count(explode(". ", $text)) The delimiter is a typical end of a sentence.
Plain simple and limited, but doesn't require any libraries.

This technique is called as web-scraping
