 New Comment:

Thank you for your bug report. This issue has already been fixed
in the latest released version of PHP, which you can download at 
http://www.php.net/downloads.php

Actually, in 5.3 it's not guarantee the exit code will equal to the last call 
to 
exit

like:
function shutdown()
{
  echo 'Script executed with failure', PHP_EOL;
  exit(0);
}

register_shutdown_function('shutdown');

exit(1);



$? will be 1.


however I fixed this issue, make 5.4 behavior same as 5.3

Description:
------------
Calling exit() in a shutdown function behaves differently between php 5.3 and 
php 5.4 (I tested with the latest stable release 5.4.5 too).

The behavior I expect is that the value returned to the calling process is the 
one from the last exit() in a shutdown function, and php 5.3 honors that 
assumption, while php 5.4 does not.

As a side note, the documentation[1] tells only that calling exit() in a 
shutdown function blocks executing further shutdown functions but it does not 
make clear what the returned value will be.

[1] http://www.php.net/register_shutdown_function

Test script:
---------------
<?php

# This script behaves differently between php 5.3 and php 5.4
# Test it with php command line:
# $ php test_exit_in_shutdown_function.php; echo $?

function shutdown()
{
  echo 'Script executed with failure', PHP_EOL;
  exit(1);
}

register_shutdown_function('shutdown');

exit(0);

Expected result:
----------------
The return value is the one from the exit() inside the last shutdown function, 
this is the php 5.3 behavior:

$ php test_exit_in_shutdown_function.php; echo $?
Script executed with failure
1

Actual result:
--------------
In php 5.4.5 the return value from the exit() inside the shutdown function is 
ignored:

$ php test_exit_in_shutdown_function.php; echo $?
Script executed with failure
0
