How can we compare two strings in PHP?

Here is a short function you can use to diff two arrays. It implements the LCS algorithm: It generates two arrays: mask array: contains numbers. 0: unchanged, -1: removed, 1: added. If you populate an array with characters, it can be used to compute inline difference.
Is there a way to render HTML version of a diff?
It has a static function to render a HTML version of the diff. It’s a first version, and likely to be improved, but it works just fine as of now, so I am throwing it out there in case someone needs to generate a compact diff efficiently, like I needed. Show activity on this post.
