Is it possible to parse mobile numbers from the site?

Question

Parsing

Good day! There is a need to get numbers from one site. Or rather from their server. The site has its own applications, where it is necessary to enter a mobile phone number and then confirm it in order to use the application. So, is there any way to get these numbers? As I understand it, it is necessary to work with regular expressions (php)

ps I apologize for such a stupid explanation. I am not strong in this topic.
