Description:
------------
Setting CURLOPT_STDERR to fopen('php://output', 'w') will write curl debug output.
One would await that setting it to fopen('php://memory', 'w') would store it in the memory and it would be available after a rewind. That is not the case, instead, a warning is raised:
Warning: curl_setopt(): supplied argument is not a valid File-Handle resource in
is php://output a valid file handle resource?
This is very confusing and it should be possible to store the output in the memory.
Test script:
---------------
$handle=curl_init('http://google.com');
curl_setopt($handle, CURLOPT_STDERR, fopen('php://output'));
curl_exec($handle);
curl_setopt($handle, CURLOPT_STDERR, $output=fopen('php://temp'));
curl_exec($handle);
rewind($output);
var_dump($output);

Your description and your test script don't match. The first mentions "php://memory", the script uses "php://temp".
Additionally, you don't specify open modes in the test script.
Seeing the source code, there's a small error in that persistent resources are not accepted (ZEND_FETCH_RESOURCE2 should have been used), but it should not cause the problem you're describing.
Please fix the problems with your bug report.

Anyway, this works here:
$handle=curl_init('http://www.google.com/');
curl_setopt($handle, CURLOPT_VERBOSE, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_STDERR, $o = fopen('php://temp', "w+"));
curl_exec($handle);
rewind($o);
echo "output: ".stream_get_contents($o);
php://memory doesn't work because that stream cannot be cast into a stdio FILE, which curl apparently requires.

Fixed test script, now with example.com.
$handle=curl_init('http://example.com');
curl_setopt($handle, CURLOPT_VERBOSE, true);
curl_setopt($handle, CURLOPT_STDERR, fopen('php://output', "w+"));
curl_exec($handle);
curl_setopt($handle, CURLOPT_STDERR, $output=fopen('php://temp', "w+"));
curl_exec($handle);
rewind($output);
var_dump(stream_get_contents($output));
Please use var_dump. You will see that it's empty. There should be two outputs:
- the one directly written to STDOUT
- one with string(n) and wrapped by var_dump's quotes
but the latter is empty:
string(0) ""
I tried both memory and temp

Right.
The problem was that I was testing on Windows, where this works.
I've just tested in Ubuntu, and indeed the string was empty there. However, I didn't get the warning you've described.

I didn't get the warning in my latest run. It could stem from the missing open modes which would be weird but possible.
