Include and php_self

[Pjotr Wedersteers]

Hello again,

I have a page visit tracker script created after a video tutorial on writing
your own tracker.
<?PHP
// consider dbconnection already in place
$page = $_SERVER["PHP_SELF"];
$IP = $_SERVER["REMOTE_ADDR"];
$date_auto = time ();
$query = "INSERT INTO tracker (page, IP, date_auto ) VALUES ('$page', '$IP',
'$date_auto')";
mysql_query ($query, $db_connection);
mysql_close ($db_connection);
?>

In the pages I want to track according to the tut all I have to do is add
<?php include ('http://wwwmyserver.com/tracker.php'); ?>

So I did. The weird bit is: in the tutorial the db lists the calling page's
name as PHP_SELF, but in my version it always shows the name of the
tracker.php script itself. I know I can use http_referer to get the info
about the page anyway, but can anyone explain WHY these results differ ? My
script is basically an identical copy of the tutorial script...

TIA,
Pjotr

$_SERVER['PHP_SELF'] always contains the name of the file that includes
other files, or the file itself when it's retrieved from a remote source
(like in your case).

The tutorial probably uses PHP_SELF as an example value to indicate the page
name.

BTW, another worakround would be to define the page variable before
inclusion:

<?php
$page = "tracker.php";
include ("http://wwwmyserver.com/tracker.php?page=$page");
?>

Thanks, that cleared up that mystery. Remote file. I was stomped. No more!
