[PHP] Statistics
I'm trying to develop a set of functions that can handle the statistics
of a website. I want them to be as flexible as possible, and i want to
be able to have several different views (day, week, month, year). For
example if i wanted to know how many visitors, visits and page hits
there was each month last year, i could call the function like this:
$months = Statistics::getStats(STAT_VIEW_YEAR, 2004);
foreach ($months as $month) {
echo $month['visitors'];
// ...
}
I'm thinking of doing it like this:
?php
class Statistics
{
public static function logPageView ()
{
global $db; // $db is just a MySQL object interface
$ip = $_SERVER['REMOTE_ADDR'];
$ex = STATS_SESSION_EXPIRE;
$result = $db-query(UPDATE `statistics` SET `visit_end` = NOW() AND
`hits` = `hits`+1 WHERE `ip` = '$ip' AND NOW()-`visit_end` $ex ORDER
BY `visit_start` DESC LIMIT 1);
if ($db-affectedRows() !== 1) {
$db-query(INSERT INTO `statistics` (ip, visit_start, visit_end)
VALUES ('$ip', NOW(), NOW()));
}
}
public static function getStats ($view = STATS_VIEW_DAY, $date)
{
global $db;
switch ($view) {
case STATS_VIEW_YEAR:
$sql = YEAR(visit_start) = $date GROUP BY MONTH(visit_start) ORDER
BY MONTH(visit_start);
break;
// More cases
default:
return FALSE;
}
return $db-query(SELECT COUNT(DISTINCT ip) AS visitors, COUNT(*) AS
visits, SUM(hits) AS hits FROM `statistics` WHERE . $sql)-fetchArray();
}
}
?
Is there a simpler way of approaching this?

You can save yourself a lot of time and effort by installing something like analog or webalizer (both free), unless ofcourse your hosting company is ripping you off by not giving access to the raw log files. The other factor you would want to consider is that inserting into a mysql database is much slower than retrieving from it particularly when you have lots of indices - you will need plenty of them if you are going to build any kind of report. -- Raditha Dissanayake. http://www.radinks.com/sftp/ | http://www.raditha.com/megaupload Lean and mean Secure FTP applet with | Mega Upload - PHP file uploader Graphical User Inteface.

Re: [PHP] Statistics function
the connection will close when you hit cancel but the PHP code can continue running if you choose. Really?!? How do you choose to have the PHP script continue even if a browser leaves/dumps? I've always wanted to do that. Didn't know it was possible. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[PHP] Statistics function
Hello everybody, How does the behind the scenes work by PHP exactly go? Does the PHP thread remain active so long as the information is sent to the visitor? Or will PHP parse the code and send it to Apache which will send the data to the user itself? The reason that I'm asking this is I'm writing a statistics add-on for one of my sites and was wondering whether the code below would give the time in which PHP parses the code or in which the data gets streamed to the user. $time_one = microtime(void); fpassthru($file); $time_two = microtime(void); // + here will be the code to calculate the difference //betweeen $time_one and $time_two Would I get information about my server (parsing time) or would I get some information about the requesters internet connection (how fast will my files get to the user). Both would be pretty important! PS What are the advanced statistics programs out there? I wouldn't mind seeing a sample report (any commercial or non-commercial). Thanks in advance in advance!

1 Apache receives the request and determines that it's a PHP script.
2 PHP parses your code
3 PHP executes your code
4 PHP passes output back to Apache
5 Apache sends output to the browser (optionally through things like SSL)
6 Apache finishes request (e.g. logs it, closes a non-persistent connection)
The catch is that steps 4/5 may repeat - this depends on your output buffering
setup. PHP can wait and send everything when the script finishes, send output
in blocks or send every output from each echo/print immediately. (PHP can also
do things like compress that output on the fly, but that's a separate
conversation)
The reason that I'm asking this is I'm writing a statistics add-on for one of
my sites and was wondering whether the code below would give the time in
which PHP parses the code or in which the data gets streamed to the user.
You'd get the time needed to read the file and either send it or add it to the
output buffer (depending on your output buffer config as mentioned above). By
the time your code is executed, PHP will have already parsed your script (with
the exception of things like conditional / variable include()s and require()s),
so you'd only get the time required to execute the code, not parse it.
If you want to get round-trip times including transmission to the user, you'd
need to have some way of getting the user's browser to record a second request,
which introduces a lot of potential variables.
It might be interesting to see how something relying entirely on client-side
calculation like the code below would compare with other approaches (e.g.
Header("Location: measure.php?start=" . time()) where measure.php just does
$elapsed = time() - $start). It should remove almost all of the server-side
latency and, in theory, would give some reasonable indication of how long it
takes to transfer a file over the intermediate network connection, which would
give you a reasonable idea of available bandwidth.
(Disclaimer: completely untested code written just now which has never been
seen by anything other than vi. Caveat programmer.)

script lang="javascript"
Start = new Date();

}
/script
