Description:
------------
I want to start a php script in background. 
I have a page that starts the php-win.exe passing parameters and it must not wait for the result.

example: exec ("c:/php/php-win.exe test.php")
where test.php is the script that must run in background.

I want that my start page does not wait the execution of php-win.exe.

I made a lot of tests using exec, system, shell_exec etc and changing parameters.

examples:
exec ("c:/php/php-win.exe test.php &");
exec ("c:/php/php-win.exe test.php > out");
exec ("c:/php/php-win.exe test.php 1> out 2>out &");
exec ("start c:/php/php-win.exe test.php > out");
etc. etc.

but nothing.

2 strange things:
1) in the past using php4 it worked fine.
2) if i try to start another command (not php-win.exe) it works fine 
(example: exec("test.exe &")): the process starts in background and the page doesn't wait.


Expected result:
----------------
expected result:
the php script starts and run in background
the page doesn't wait the end of php-win.exe

Actual result:
--------------
The start page waits until the script ends
