[php-src] Issue #11090: curl - fail-with-body support

Issue: https://github.com/php/php-src/issues/11090 Author: rbro ### Description In cURL 7.76.0, a new option --fail-with-body was added: https://daniel.haxx.se/blog/2021/02/11/curl-fail-with-body Would it be possible to implement similar functionality in PHP's curl library? I posted the below in Stack Overflow in 2021: https://stackoverflow.com/questions/68246166/how-to-retrieve-curl-response-on-error-in-php As I wrote in the post, I'm looking to: - on success, have the http response pass directly to the user's browser - but on error such as a http 500 error, get the http response body into a variable in PHP I don't want to use CURLOPT_RETURNTRANSFER because on success, the PDF file returned is large and it would be inefficient to first save the file to a PHP string or a temp file, only to just echo it to the user's browser. What I'm looking for is an option called CURLOPT_RETURNTRANSFERONERROR, where the response data is only returned on a http error. Thank you for your help. Ryan
