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
