automatic mail notification

[Tube]

Hi, I am looking for a script that will send a mail to a specified address at the moment a certain IP number visited my website.
Can imagine it would be something like:
If ip= XXXXXXXXX then send mail to [e-mail]

I am not familiar enough yet to figure it out myself. Maybe it's not this simple, but who can tell me? 😕

if ($REMOTE_ADDR == 123.12.1.0)
mail('[e-mail]', 'this bastard is here!', 'Yes, he has come at last!');

I have tested his one,

<?php
if ($REMOTE_ADDR == 212.129.128.83)
mail("[e-mail]", "a sample subjectline", "dit is een testje");
?>

but I get an error:

Parse error: parse error, unexpected T_DNUMBER in /home/httpd/html/www.goofyroof.nl/HTML/testmail.php on line 2

If I leave out the If line, the mail works good so somewhere there should be something wrong in that line
Any idea what it might be?

Yeah, sorry, I've missed quotes. Sure that's my fault 🙂
