If you are not your own ISP mostly you don't can access in the log files. But for real optimising your webpage you have to know from where did the user come from and where did he exit your pages.
That causes we will build our own access.log

Listening 1
Code:

<?
$ref=$_SERVER['HTTP_REFERER']; //where does he come from
$user=$_SERVER['HTTP_USER_AGENT']; //Browser?
$wo=$_SERVER['REQUEST_URI']; //current page?
$wann=date("D M d, Y G:i"); //when?
$ip = $_SERVER["REMOTE_ADDR"]; //Who?
?>


Users get their IPs often dynamicly and maybe behind a simply proxy

Listening 2
Code:

<?
if($_SERVER['HTTP_X_FORWARDED_FOR'] != ""){
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
$proxy = $_SERVER["REMOTE_ADDR"];
$host = @gethostbyaddr($_SERVER["HTTP_X_FORWARDED_FOR"]);
}else{
$ip = $_SERVER["REMOTE_ADDR"];
$host = @gethostbyaddr($_SERVER["REMOTE_ADDR"]);
$proxy = "none";
}
?>


Now we have to save the data.

Listining 3
Code:

<?
$m_user='user.txt'; //Where save it?

$input =$wann;
$input .=" on page:";
$input .=$wo;
$input .=" come from: ";
$input .=$ref;
$input .=" User ";
$input .=$ip;
$input .="  ";
$input .=$user;
$input .="  Proxy: ";
$input .=$proxy;
$input .="  Host: ";
$input .=$host;

$f=fopen($m_user, 'a'); //If there is no file create it.
fputs($f,$input ."\n");
fclose($f);
?>


Now patch that all together

Listining 4 log.php
Code:

<?
$m_user='user.txt';
//if(!file_exists($m_user)){$fh=fopen($m_user, 'w'); fclose($fh);}

$ref=$_SERVER['HTTP_REFERER'];
$user=$_SERVER['HTTP_USER_AGENT'];
$wo=$_SERVER['REQUEST_URI'];
$wann=date("D M d, Y G:i");

if($_SERVER['HTTP_X_FORWARDED_FOR'] != ""){
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
$proxy = $_SERVER["REMOTE_ADDR"];
$host = @gethostbyaddr($_SERVER["HTTP_X_FORWARDED_FOR"]);
}else{
$ip = $_SERVER["REMOTE_ADDR"];
$host = @gethostbyaddr($_SERVER["REMOTE_ADDR"]);
$proxy = "keiner";
}

$input =$wann;
$input .=" auf Seite:";
$input .=$wo;
$input .=" kam von: ";
$input .=$ref;
$input .=" Besucher: ";
$input .=$ip;
$input .="  ";
$input .=$user;
$input .="  Proxy: ";
$input .=$proxy;
$input .="  Host: ";
$input .=$host;

$f=fopen($m_user, 'a');
fputs($f,$input ."\n");
fclose($f);
?>


Now put the access log into owr page

Listening 5
Code:

<?
// mein stuff
......
//
include "log.php";
?>


If there is much traffic you better save the datas in a Database

For more traffic the MySQL variant

The '' are single ' not "

Code:

CREATE TABLE stats (
id int(11) NOT NULL auto_increment,
wann varchar(22) NOT NULL default '',
wo varchar(50) NOT NULL default '',
ref varchar(100) NOT NULL default '',
ip varchar(15) NOT NULL default '',
user varchar(100) NOT NULL default '',
proxy varchar(15) NOT NULL default '',
host varchar(50) NOT NULL default '',

PRIMARY KEY (id),
UNIQUE KEY (id),
KEY id_key(id),
KEY wann_key(wann),
KEY wo_key(wo),
KEY ref_key(ref),
KEY ip_key(ip),
KEY user_key(user),
KEY proxy_key(proxy),
KEY host_key(host)
)
TYPE=MyISAM;


Against SQL-INJECTION mysql_escape_string();
Code:

<?php
@mysql_query(sprintf("INSERT INTO %s('wann','wo','ref','ip','user','proxy','host') VALUES('%s','%s','%s','%s','%s','%s','%s')",
$table,
mysql_escape_string($wann),
mysql_escape_string($wo),
mysql_escape_string($ref),
mysql_escape_string($ip),
mysql_escape_string($user),
mysql_escape_string($proxy),
mysql_escape_string($host)
), $link)
or die_error(mysql_error($link));
?>


Reload-Blocker

Code:

<?php
//some IP time thing
if(mysql_num_rows($result_von_vorher)==0){
//Daten eintragen
@mysql_query("INSERT INTO...");
}


What does the log show

Usefull is the my mysql Function count(); und GROUP BY

Don't forget, that I used the variable user for the browser.

Code:

<?PHP
$result= @mysql_query(sprintf("SELECT user, count(*) AS count GROUP BY user ORDER BY count DESC",
$table
), $link)
or die_error(mysql_error($link));
?>


I'd like to see your complete solutions.
