Gathering of statistics on PHP

Statistical data on visitors of a site bring not not enough advantage. On statistics it is possible to adjust design of a site according to the sanction of the majority of visitors, to adjust design to a browser on which come the most part of visitors and it is simply interesting, who looks on you on a site, from under what OC, and it can the search robot jandeksa or gugla? Though some systems of tracking visitors are cherezvychajno complex , but with the help of rather simple system it is possible to receive curious data on visitors of a site. I shall show as to make with a kind simple magazine of visitings of a site with help PHP and cookies (MySQL it is not required). Besides it is possible to expand my example easily.

For that the system would work, it is necessary to build a script of statistics in each page. Well or in those pages, which statistics of visitings you want to see. Our script will write down the following data:

? A browser + OC (HTTP_USER_AGENT)

? IP (REMOTE_ADDR address

? A host (REMOTE_HOST)

? Page - refferer (HTTP_REFERER)

? Time of visit (date (" d.m. Y H:i:s "))

? Required (REQUEST_URI address

Even these data, I think, will be rather interesting to web designers. So, we shall start. The script will be called sniffer.php. I shall result the text of all script and I shall add it to plentiful comments:

<? php

// sniffer.php

// Protection against direct start

// A script whom that the stranger

if (eregi ("sniffer.php", $PHP_SELF)) {

Header (" Location: index.php ");

die ();

}

extract ($HTTP_GET_VARS);

extract ($HTTP_POST_VARS);

extract ($HTTP_COOKIE_VARS);

extract ($HTTP_SERVER_VARS);

// This fragment of a code has been borrowed

// From system PHP Nuke;)

// Further I declare variables

$fileName="stat.txt "; // a name of a file with statistics

$maxVisitors=30; // quantity{amount} of the recordings displayed

// At viewing statistics

$cookieName = "visitorOfMySite"; // a name kuki

$cookieValue = "1"; // value kuki

$timeLimit=86400; // term in seconds which should

// To pass from the moment of last visiting a site, what

// The information on the visitor has entered the name repeatedly. It

// Value is equal to 1 day, i.e. the same visitor

// Enters the name in statistics of times in one day. If

// This variable to equate to zero will be taken into account

// All visitings the same visitor

// The variables responsible for display further follow
