/*    PHP3/mSQL Page Log v1.0 by Rob Fisher
    4 June 1998

    This script is provided with no guarantees that it will either
    work properly or not trash your machine. So don't blame me if
    it does. It works great for me though, and you can do whatever
    you want to it in the name of free software.

    It's not very general and will need adapting to work on your
    site. That's because I pulled it straight out of my web directory,
    annotated it, and stuck it on PX. If you need help, you can
    mail me. (Details below.) It would be nice to hear from anyone
    who uses this code, so why not sign my guestbook at
    http://helios.hud.ac.uk/web/ ?

    I wrote this script because I wanted to move from PHP/FI 2.0.1
    to PHP3, but I didn't want to lose the page access logging
    facility built into the former package.

    I also wished to make the changeover as smooth as possible,
    without starting counting hits from zero. To do this, I could
    have written a script to use and add to the existing PHPFI
    database on my system, but I decided to log only the information
    I wanted to use, and to take the final state of my PHP/FI logs
    as the starting point for my PHP3 ones.

    This script is intended to be include()d at the end of a page,
    just before the </BODY> tag. It appends a footer stating your
    name, the number of hits to the page, the time of the last hit
    and the date when the page was last updated. It also creates
    a link to the W3C HTML validator, so you are always only one
    click away from validating any page on your site.

    To use my script, you'll need to create a php3 database using the
    command "msqladmin create php3". (No quotes.) then create a table
    with the following commands:


        CREATE TABLE log (
            fname    CHAR(128),
            hits    INT,
            last_hit    INT
        )\g

        CREATE UNIQUE INDEX idx ON log(fname)
        \g

    As you can see, this is a much more spare form of access logging
    than that built into PHP/FI, recording only the page name, the
    amount of times that page has been hit, and the date and time of
    the last hit. I don't need the extra information that PHP/FI logs,
    and keeping it builds up huge mSQL tables. If you want to record
    more data, it's not difficult to change this script.

    If you don't want to lose those hits you've worked so hard
    to acquire, when this script checks for hits to a page and finds
    none, it looks to see if an old PHP/FI access log exists for that
    page, and, if so, takes the number of hits and the last access
    from the correct table, moving that data into its own database.

    If you're going to check for old PHP/FI access logs, you need
    to assign the variable $UID to the UID you gave when initialising
    the phpfi database. If you don't want this check to be carried
    out, set the $check variable = false or remove the appropriate code */

    $check = true;
    $UID = 264;

     /* Set up a few other variables just to keep things clear */

    $author =  "Rob Fisher";         /* your name here! */
    $mail =  "[e-mail]";     /* your e-mail address here */
    $server =  "helios.hud.ac.uk";     /* your server URL here */
    $host = helios;             /* the machine running msql2d */
    $root =  "/spare/apache/htdocs";  /* your server's document root */
    $name = $SCRIPT_FILENAME;     /* the page including this file */
    $now = mktime();         /* the present time */


     /* Is there an mSQL server in the house? */

    if (msql_connect($host) == false):

        look for old PHP/FI logs?*/
