When you copy file to _already_ existed file-target, then info of this file-target will be cached before rewrite. Workaround here is usage of clearstatcache(). Also other problem is that copy() function is not listed in list of cached functions in manual for clearstatcache(). As i understand from source code, the problem is that copy() uses php_stream_stat_path_ex() [ _php_stream_stat_path() ] function which stores stat info in cache. Correct solutions are: 1. add parameter to php_stream_stat_path_ex() to not store info to cache and call it for destination path in php_copy_file_ex() 2. clear cache after successfull call of php_stream_stat_path_ex() for destination path in php_copy_file_ex(). Reproduce code: --------------- <?php $source = '/t1.t'; $target = '/t2.t'; file_put_contents($source, 'aaaaaaaaaa'); file_put_contents($target, 'a'); clearstatcache( true ); copy( $source, $target ); var_dump( filesize($target) ); ?> Expected result: ---------------- int(10) Actual result: -------------- int(1) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47126&edit=1
