Description:
------------
The CLI version of PHP does not return the integer exit status to the shell when using 'exit(integer);' from within the script. PHP will always return 0 (or 255 probably).

The manual says that it would do.

Calling 'exit("string");' (with a string as parameter) it works as expected and as mentioned in the manual.

Reproduce code:
---------------
This is what I'm trying to do:

file1.php
---------
<?
system("php ./file2.php", $rv);
fwrite(STDOUT, $rv."\n");

system("php ./file2.php -- -param", $rv);
fwrite(STDOUT, $rv."\n");
?>

file2.php
---------
<?
if($argc < 2)
    exit(1);
else
    exit(0);
?>


Expected result:
----------------
Execute:

# php ./file1.php

Output should be:
1
0


Actual result:
--------------
Buggy result is:
0
0

Works fine for me:

# php t.php ; echo $?
222

t.php:
<?php exit(222); ?>

Thank you for your reply ...

I must admit that your example does work.

And I'm sorry, because even my own example works as one would expect. I didn't try it myself, because I assumed that it would NOT work. 

I'm using pretty much the same code in a larger application where it definately does NOT work. In that application I'm working a lot with 'exec()' and 'system()' and also using IO redirections. It might have to do with that, but I have not yet been able to isolate the real cause from within a smaller context.

So for now I'd say that you can close the issue. As soon as I know where the problem comes from, and it has to do with PHP, I'd happily re-open this issue if you don't mind.

Again, I'm really sorry that I wasted your time just because I made big mistake.

PHP-CLI is somewhat cool and I hope it will replace Perl some day, on Unix-like OS. Thanks for making it...
