The best solution is probably using crontab to schedule your job to run
at the same time each month, eg 03:27 on the 3rd

Failing that, you could use a semaphore file and the getdate, filemtime
and touch functions, like this:

<?php

$sf = "semaphore-file-name";
$newmonth = false;
$last = @filemtime($sf);
if ($last) {
$then = getdate($last);
$now = getdate();
if ($then["mon"] != $now["mon"]) {
$newmonth = true;
}
}
else {
$newmonth = true;
}

if ($newmonth) {
touch($sf) or die "unable to modify file\n";
// do once a month stuff
}

?>
