Pagestats v1.0

Copyright 1998 Cary Collett. Use it freely, distribute it freely, tell me
how great it is freely and send me any cool mods you come up with for it,
freely.

Changes

1.1 Now using SCRIPT_FILENAME everywhere instead of SCRIPT_NAME. Using
SCRIPT_NAME could result in collisions if virtual hosts are being used.
I.e. hits for www.foo.com/index.html and www.bar.com/index.html would
both be collected for the same URI. Of course this makes the column
name URI a misnomer. Change it if it really bothers you. ;-)
*/
/*

A simple script to be included that reports hits, last modification
and when the hit counting started. You'll need MySQL support.
Though it should be easy to port this to any decent DBMS (mSQL
might be a little sticky becuase of it's severely limited
feature set; I don't use it anymore so I don't know for sure.)

This mysql table must exist in the database 'php' (or you can edit
stuff to suit you).

create table pagestats (
uri varchar(96) primary key,
hits bigint not null default 0,
since datetime
);

It defines several variables:

$hits = Number of hits counted
$since = full blown date & time since the counter started
$lastmod = full blown date & time of the last modification (ctime) of
the file

The following Unix epochs are set. Users can use these if they don't like
default format.

$sincesecs = Unix epoch of since
$modsecs = Unix epoch of lastmod

An example of usage:

1. Put this file somewhere in your PHP include path.
2. Stick something like this in your page:


<? include("pagestats.php3"); ?>

<? echo $hits . " hits since " . date('F d, Y',$sincesecs); ?>.
<p>
Last modified: <? echo $lastmod; ?>
<p>


*/

$link = mysql_pconnect('localhost','logger','');
mysql_select_db('php',$link);

$qs = "UPDATE pagestats SET hits=hits+1 WHERE uri = '$SCRIPT_FILENAME'";

$r = mysql_query($qs,$link);

if (mysql_affected_rows($link) < 1) {
/* oops, no row for this page, create one */
mysql_query("INSERT INTO pagestats VALUES ('$SCRIPT_FILENAME',1,SYSDATE())",
$link);
}

$res = mysql_query("SELECT hits, UNIX_TIMESTAMP(since) as since FROM pagestats
WHERE uri = '$SCRIPT_FILENAME'",$link);

$sincesecs = mysql_result($res,0,'since');
$modsecs = filectime($SCRIPT_FILENAME);

$hits = mysql_result($res,0,'hits') + 1;

/*
see the date() docs if you want to change this
The format 'l F d, Y h:i:s A' makes dates like this:
Friday May 08, 1998 04:22:08 PM
*/

$dateformat = 'l F d, Y h:i:s A';

$since = date($dateformat,$sincesecs);
$lastmod = date($dateformat,$modsecs);
?>
