PHP - Debugging Curl
curl, debugging, php
Solution
You can enable the `CURLOPT_VERBOSE` option:
curl_setopt($curlhandle, CURLOPT_VERBOSE, true);
When `CURLOPT_VERBOSE` is set, output is written to STDERR or the file specified using `CURLOPT_STDERR`. The output is very informative.
You can also use tcpdump or wireshark to watch the network traffic.
Problem
I'd like to see what the post fields in the request are before I send it. (For debugging purposes). The PHP library (class) I am using is already made (not by me), so I am trying to understand it. As far as I can tell, it uses `curl_setopt()` to set different options like headers and such and then it uses `curl_exec()` to send the request. Ideas on how to see what post fields are being sent?
