$ php -v
4.2.0
$ php -q
<?php
exit(5);
?>
$ echo $?
255

exit(n) always reports 255 (or -1) as exit status to the OS, regardless of the value it is passed as argument.

The correct behavior according to the documentation would be to report n as exit status, or echo n if n is a string.

The only workaround I could find is to use return from the global scope.

Thank you :)

I think I broke this, so I'll fix it too :)

Experiencing same problem on 4.2.0/Linux. Return from global scope does not seem to work for me though or else I would use it as an alternative.

Is this fixed in CVS?

Here's another workaround for you if you have --enable-pcntl: 
 
$ php -q 
<?php 
pcntl_exec("/bin/sh", array("-c", "exit 123")); 
?> 
$ echo $? 
123

The pcntl_exec worked good...Thank you.

Ideally the exit status would work as discussed on the dev mailing list...exit(int) sets status as integer, exit(string) prints string.

just tested on PHP 4.3.0-dev (cli) and still no exit status...;)

Know where I should start hacking?? /sapi/cli ?

Thanks for the pcntl tip!

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.
