So the problem isn't really that the file is not copied, but rather that the information statcache is stale. ------------------------------------------------------------------------ [2013-10-10 02:52:55] haoustc at gmail dot com that seems a problem. ------------------------------------------------------------------------ [2013-09-18 17:54:26] flack at contentcontrol-berlin dot de Argh, third time's the charm: file_put_contents($dst, file_get_contents($src)) is working ------------------------------------------------------------------------ [2013-09-18 17:53:00] flack at contentcontrol-berlin dot de Typo: Should read file_put_contents($src, file_get_contents($dst)) for the version that works ------------------------------------------------------------------------ [2013-09-18 17:51:33] flack at contentcontrol-berlin dot de Description: ------------ See the script below. The expected output is int(4) instead, I get int(0) I tested on the Ubuntu packages for php 5.3.10, 5.4.4 and 5.5.3. When I use file_put_contents($src, $dst) instead of copy(), it works as expected. Also, when I use fopen() and stream_copy_to_stream(). Only the plain copy() function doesn't behave as expected. Everything is on the same hard disk and was tested on three different machines (Ubuntu 12.04, 13.04 and Debian 7). Test script: --------------- $src = '/tmp/file.txt'; touch ($src); file_put_contents($src, 'test'); $dst = tempnam('/tmp', 'dst'); copy($src, $dst); var_dump(filesize($dst)); Expected result: ---------------- int(4) Actual result: -------------- int(0) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65701&edit=1
