OK, here it goes: <?php $socket = fsockopen("localhost", 80, $errno, $errstr, 30); if (!$socket) { echo "$errstr ($errno)<br />\n"; } else { $out = "GET / HTTP/1.1\r\n"; $out .= "Host: localhost\r\n"; $out .= "Connection: Close\r\n\r\n"; fwrite($socket, $out); } $fp = fopen("data", "w"); stream_copy_to_stream($socket, $fp); ------------------------------------------------------------------------ [2009-11-16 22:08:27] stas at zend dot com Description: ------------ If I use stream_copy_to_stream with source stream being not file (say, HTTP socket) then I get this warning: Warning: Invalid CRT parameters detected This is because in _php_stream_copy_to_stream_ex() php_stream_stat() is applied to source stream, which goes to php_sockop_stat which calls fstat, which produces "invalid parameter" pseudo-exception. Reproduce code: --------------- $socket = open_http_socket(); $fp = fopen("data", "w"); stream_copy_to_stream($socket, $fp); Actual result: -------------- Warning: Invalid CRT parameters detected ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50196&edit=1
