That's not possible. You cannot pass a string as stream. The following should work: daniel@daniel-laptop:~$ cat test.php <?php $stderr = fopen('php://stderr', 'w'); fwrite($stderr, 'Error 1' . PHP_EOL); fwrite(STDERR, 'Error 2' . PHP_EOL); echo 'Normal echo'; daniel@daniel-laptop:~$ php test.php > /dev/null Error 1 Error 2 daniel@daniel-laptop:~$ ./src/php-5.2.12/sapi/cli/php test.php > /dev/null Error 1 Error 2 -- Daniel Egeberg
