How to log CURL requests in PHP?

Question

PHP

Good afternoon.
There is a system:
Ubuntu 14.04 / PHP 5.6 (FPM)
There are many CURL requests that are executed in a PHP script. Is it possible to somehow globally track requests and responses from curl using ubuntu and write this data to a file?

Answer 1

tcpdump
or install runkit and reassign curl to your handler :)
