algorithm

Does anyone know where can i find an explanation and implementation of the diff algorithm. First of all i have to recognize that i'm not sure if this is the correct name of the algorithm. For example, how Stackoverflow marks the differences between two edits of the same question?

ps: I know C and PHP programming languages.
