Failure with blank 'curl_error' executing request.

[raintonr]

I'm having problems with this library. I have traced this to the curl_exec call failing.

Unfortunately curl_error is returning a blank string so I really have no idea as to what is going wrong. This is very frustrating and don't know whether this is a PHP bug (am on Centos with PHP 5.4.16) or something else.

I will try and figure out why the error is blank and report back.

OK, so I discovered if we add curl_errno in there too then it gives a number that lead me to the problem. The response needs updating to (or similar):

$response = 'Curl error: ' . curl_errno ( $c ) . ' - ' . curl_error ( $c );

@raintonr - what is the actual errno?

[raintonr]

It depends of course. In my case it was 77 because the path to my CA file was incorrect.

[calcinai]

Oh right, so this is no longer an issue? It sounded like you were stuck on the error!

[raintonr]

I was stuck, but was only able to become un-stuck because I modified the code to output the errno. My point is, to output a blank string on error is useless and the library should be modified to include the errno to better aide debugging.

You're preaching to the choir! I wish that was all that needed fixing...
