Hi everybody. I need to use exec() to run a background php script, but
it's not working properly. Take a look at this sample:

a.php
<?

echo ' File A (1) ';

exec('php b.php > output.txt &');

echo ' File A (2) ';

?>

b.php
<?

echo 'File B';

?>

output.txt (begins with 64 null bytes before the following)
File A (2)

I would expect the output's content to be "File B", but it's not
happening. I came across this problem because I have a mailing
application which stopped working after being moved to a new host. The
messages were sent by a background script launched on user's demand.
Like this:

SendMessages.php
<?
...
exec('php Daemon.php -x ' . $USERID . ' > /dev/null &');
...
?>

Now it won't work, and I got no clue about what's going on. What now?

Thank you.

Try not use the short open tag. Use <?php

Not really. The server allows short open tags. So, nothing changed.
