Previous Comments: ------------------------------------------------------------------------ [2009-04-17 11:08:30] jani@php.net From streams.c: "in the event that the source file is 0 bytes, return 1 to indicate success because opening the file to write had already created a copy" Looks like yet another design flaw in the streams API. ------------------------------------------------------------------------ [2009-04-16 23:52:46] robots at shad dot pp dot ru Description: ------------ Function returns 1 even if used to copy empty stream. Reproduce code: --------------- <?php // Creating empty file $src = fopen('srcfile.tmp', 'w+'); fclose($src); $src = fopen('srcfile.tmp', 'r'); $dst = fopen('dstfile.tmp', 'w+'); echo stream_copy_to_stream($src, $dst); fclose($src); fclose($dst); ?> Expected result: ---------------- 0 Actual result: -------------- 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47997&edit=1
