How to cut contact information from a string?

Question

PHP

Hey! There is a marketplace, and a supplier-client correspondence module. You need to parse all messages and cut them out: emails, phones, urls.
I wrote a basic function that does the job. But when clients start to bypass it and write something like:

mybox dog mail.ru
Plus seven 912 seven hundred fourteen seventy one ninety nine
SMS 7.9.1.2.1.2.3.4.5.6.7

...then my parser is powerless. Can anyone come across a good ready-made solution? Of those that I have seen, the parser on AirBnB is perfectly made, it is very difficult to deceive it.
PS Of course, I understand that 100% recognition of contacts can never be done, but I need to weed out the largest possible number of such "tricks".

Answer 1

Well, start supplementing your parser with the words "dog" with numerals, strange combinations of all sorts of types 3 digits through a dot, over time you will have a system that distinguishes almost everything.

Answer 2

On fl.ru a few years ago there was an unsuccessful idea - to read all messages of users.
And so, for me, the chance to make such a parser is a utopian idea. in extreme cases, you can send a picture, or instead of punctuation marks at the end of a sentence, give a number. You have no chance to prevent the transfer of contact data. Deal with it. And make your service more interesting.
