How to open a site blocked by company policies through your site?

Question

proxy

All sites are working, but blocked by company policies, and when you go to the site, a stub appears that the site is blocked, the site category, ip, and so on.

There are services like https://anonymouse.org and the like.
I'm thinking of making a similar bridge across my site. But I do not quite understand where to look and how this happens.

Tried through iframe, but of course it is also blocked through it.

Tell me how to do this?

In general, by googling "php web proxy", I came across a wonderful library miniProxy .
This solved my issue.
