How to link wheel

[eThno]

Hello,

I am looking for how to add random links in a text.
For example add 4 links at random from a file and output a text with links to everywhere.

Or replace keywords in a text through links at random.
I try to 'replace all string, but I always load the same link and not randomly.

Thank you for your answers.
