In this configuration, I cannot redirect any output data to a file.
 
Flush() after print() or echo() takes no effect.
Only when 'output_handler' is set to 'mb_output_handler'.


Reproduce code:
---------------
$ cat redirect_test.php
#!/usr/local/bin/php -q
<?php
print "Hello, world.\n";
// flush();
?>

Expected result:
----------------
$ ./redirect_test.php > result.txt
$ ls -l result.txt
-rw-r--r--  1 jkawa  jkawa  14 Sep 12 06:32 result.txt
$ cat result.txt
Hello, world.
$

Actual result:
--------------
$ ls -l result.txt
-rw-r--r--  1 jkawa  jkawa   0 Sep 12 06:40 result.txt
$ cat result.txt
$
