如何显示帖子的简短版本

Question

I'm writing a blog and I want to show short versions of posts on the main page. I assume native php string functions aren't appropriate here since posts can be large and it would take long to substr all posts in loop. So, what is the common strategy here? I hope the question is clear and specific.

I don't want to shorten posts on client side with JS, that's not an option.

Answer 1

The solution I use is to make another field in db table with posts where I put short version of post, cuted begining or something like that.

It's faster, and better, you don't have to worry about length becouse you control it, there is no problem with evenual html tags used in context, and you can have a bit diffrent text on mainpage
