Is it possible to replace email and phone number by ref. links?

Question

PHP

Greetings!
Is it possible to replace email and phone number by ref. links on the site. The number of links is 10, and for each, the number and email are replaced wherever it is.
Is there a link for more details on this? I don’t know, maybe I dug badly, but I didn’t find an answer anywhere, or maybe this is not possible.
