Register_shutdown_function does not work

[Anon]

Hi !

I'm downloading a file via ftp to my server. The file should be
destroyed IN ALL CASES when then script ends - but it isn't.

Have a look at the following code-snippet. I register "OnShutdown" as a
Shutdown-Function, but the filename isn't unlinked when the script
terminates. Calling OnShutdown directly deletes the file (just as a
"debug-test").

Any ideas, why OnShutdown isn't called when the script terminates ?

<?php

register_shutdown_function("OnShutdown");

$tmp_filename = ""; // Temp Filename on server

function OnShutdown()
{ global $tmp_filename;
if ($tmp_filename != "")
{ unlink($tmp_filename);
$tmp_filename = "";
}
}

class Download
{... class to download file
};
?>

The register_shutdown_function() is supposed to run whether your script finishes normally or not. In some installations, however, I have noticed that it only calls the specified function IF THE SCRIPT IS INTERRUPTED. That is, it only calls the function if the user presses the <STOP> button in their browser (aborts the download) before the script finishes.

For this reason, I have taken to calling the same function explicitly at the end of my scripts as well as specifying it in the connection_aborted() function and not using the register_shutdown_function() function at all.

Hope This Helps.
