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
