I just need to send one email into the future, so I figured i'd be best at using at rather than using cron. This is what I have so far, its messy and ugly and not that great at escaping:
<pre>
<?php
$out = array();
// Where is the email going?
$email = "
[email protected]";
// What is the body of the email (make sure to escape any double-quotes)
$body = "This is what is actually emailed to me";
$body = escapeshellcmd($body);
$body = str_replace('!', '\!', $body);
// What is the subject of the email (make sure to escape any double-quotes)
$subject = "It's alive!";
$subject = escapeshellcmd($subject);
$subject = str_replace('!', '\!', $subject);
// How long from now should this email be sent? IE: 1 minute, 32 days, 1 month 2 days.
$when = "1 minute";
$command= <<<END
echo "
echo \"$body\" > /tmp/email;
mail -s \"$subject\" $email < /tmp/email;
rm /tmp/email;
" | at now + $when;
END;
$ret = exec($command, $out);
print_r($out);
?>
</pre>
The output should be something like
warning: commands will be executed using /bin/sh
job 60 at Thu Dec 30 19:39:00
2010
However I am doing something wrong with exec and not getting the result?
The main thing is this seem very messy. Is there any alternative better methods for doing this?
PS: I had to add apache's user (www-data for me) to /etc/at.allow ...Which I don't like, but I can live with it.
