Summary: curl doesn't write to php://temp or /memory
Status: Verified
Type: Bug
Package: Sockets related
Operating System: Ubuntu
PHP Version: 5.3.3

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

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.

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

Anyway, this works here:
<?php
$handle=curl_init('http://www.google.com/');
curl_setopt($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.

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.

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);
