I'm trying to do some cleanup (write open files) when Linux shuts down. I thought the right method would be to trap SIGTERM and do the necessary processing. Here's my sample code:
When I run this, and press Ctrl-C, it writes "got 2" to test.txt. However, if I logout/reboot, nothing is written to the file.

register_shutdown_function
REGISTER_SHUTDOWN_FUNCTION(3) 1 REGISTER_SHUTDOWN_FUNCTION(3)register_shutdown_function - Register a function for execution on shutdownSYNOPSIS
void register_shutdown_function (callable $callback, [mixed $parameter], [mixed $...])
DESCRIPTION
Registers a $callback to be executed after script execution finishes or exit(3) is called.
Multiple calls to register_shutdown_function(3) can be made, and each will be called in the same order as they were registered. If you
call exit(3) within one registered shutdown function, processing will stop completely and no other registered shutdown functions will be
called.
PARAMETERS
o $callback
- The shutdown callback to register. The shutdown callbacks are executed as the part of the request, so it's possible to send
output from them and access output buffers.
o $parameter
- It is possible to pass parameters to the shutdown function by passing additional parameters.
o $...
-
RETURN VALUES
No value is returned.
ERRORS /EXCEPTIONS
If the passed callback is not callable a E_WARNING level error will be generated.
EXAMPLES
Example #1
register_shutdown_function(3) example
<?php
function shutdown()
{
// This is our shutdown function, in
// here we can do any last operations
// before the script is complete.
echo 'Script executed with success', PHP_EOL;
}
register_shutdown_function('shutdown');
?>
NOTES
Note
Working directory of the script can change inside the shutdown function under some web servers, e.g. Apache.
Note
Shutdown functions will not be executed if the process is killed with a SIGTERM or SIGKILL signal. While you cannot intercept a
SIGKILL, you can use pcntl_signal(3) to install a handler for a SIGTERM which uses exit(3) to end cleanly.
