How to proxy in php?

Question

PHP

Gentlemen and possibly ladies)
I have such an architecture Client <-> Web Server <-> Web API Server
.
How can I proxy (in PHP) to the client (for example, jsessionid is given to me on the Web Server, but should settle in the client's cookies)?
Thanks for the answers

Answer 1

the headers are the same as without a proxy, the only difference is that they are not transmitted by your request, but by the proxy server
