Related to Bug #76268 and Bug #70693 ------------------------------------------------------------------------ [2016-08-03 15:49:19] vonubrog at gmail dot com Same here with PHP 7.0.9 and 5.4.45. Such an annoying inconsistency :( ------------------------------------------------------------------------ [2016-04-24 06:41:21] bugs dot php dot net at ss dot st dot tc Description: ------------ When using CURLOPT_FILE, file position indicator stays in the end when the handle is a temporary stream. However the indicator is rewinded to 0 when the handle is a regular file (which seems to be a wrong behaviour). Tested in PHP 7.0.5 and 5.6.20. Test script: --------------- <?php function test($filename) { echo $filename, PHP_EOL; $fh = fopen($filename, 'w'); $curl = curl_init('http://php.net/'); curl_setopt($curl, CURLOPT_FILE, $fh); curl_exec($curl); echo ' fstat size: ', fstat($fh)['size'], PHP_EOL; echo ' ftell: ', ftell($fh), PHP_EOL; } test('regular-file.tmp'); test('php://temp'); Expected result: ---------------- regular-file.tmp fstat size: 19371 ftell: 19371 php://temp fstat size: 19371 ftell: 19371 Actual result: -------------- regular-file.tmp fstat size: 19371 ftell: 0 php://temp fstat size: 19371 ftell: 19371 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72092&edit=1
