EMAIL处理函数

function send_email()
{

Request access to the global variables we need

global $REQUEST_URI, $HTTP_REFERER, $emailaddress, $REMOTE_ADDR, $docroot;

定制发送的消息，如时间地点等.

$today = getdate();
$month = $today[mon];
$mday = $today[mday];
$year = $today[year];
$hours = $today[hours];
$minutes = $today[minutes];
$errortime = "$month/$mday/$year at $hours:$minutes";

Create the body of the email message

$message .= "404 Error ReportnnA 404 error was encountered by $REMOTE_ADDR";
$message .= " on $errortime.nn";
$message .= "The URI which generated the error is: n$docroot$REQUEST_URInn";
$message .= "The referring page was:n$HTTP_REFERERnn";

Send the mail message. This assumes mail() will work on your system!

mail("$emailaddress", "404 Error Report", $message, "From: $emailaddress"); //好，把信发出去

return;
}

下面这些是根据变量$reportlevel的设置来发信与否。

print_details();

See whether or not we should send an email report. If so, do it.

if ($reportlevel != 0)
if ($reportlevel == 1) {
if (eregi($domain,$HTTP_REFERER))
send_email(); }
else
send_email();

All done!

exit;
