This causes pear install PhpDocumentor to fail on windows. To test, create an empty file "emptyfile.php" and a non-empty file "nonemptyfile.php" in the same directory as this script, and run it: <?php var_dump(copy('emptyfile.php','newfile.php')); // bool(false) var_dump(copy('nonemptyfile.php','newfile.php')); //bool(true) ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22234&edit=1
