hi guys,

recently i've just moved to a new hosting company. my cgi doesn't work with php pages anymore, the virtual () is not working.

so, i searched the web, got this script and modified it. everything is working the same way as my previous cgi script, except that, it logs everything, even page reload.

the php script:

PHP Code:

<?php
$logfile = "log.db";
if (file_exists($logfile)) {
$handle = fopen($logfile, "r");
$log = fread($handle, filesize($logfile));
fclose($handle);
} else {
die ("The log file doesn't exist!");
}
 
$log = explode("\n", trim($log));
for ($i = 0; $i < count($log); $i++) {
$log[$i] = trim($log[$i]);
$log[$i] = explode('|', $log[$i]);
}
echo "Total Entries : " . count($log);
echo '<style type="text/css">
body {
 background-color: #000;
 color: #ffff80;
 text-align: center;
 font-size: 13px
}
.wrapper {
 width: 90%;
 text-align: center;
 margin: 0 auto;
}
a {
 color: #33ccff;
 text-decoration: underline;
}
a:hover {
 text-decoration: none;
}
table {
 width: 100%;
 border-collapse: collapse;
 border: 2px ridge #ccc;
 text-align: center;
 margin: 0 auto;
 font-size: 13px
}
td {
 background-color: #0f0f4f;
 padding: 3px;
 border: 2px ridge #ccc
}
td.a {
 width: 12%;
}
td.b {
 width: 28%;
}
td.c {
 width: 60%;
}
</style>';
echo '<div class="wrapper"><table>';
foreach ($log as $logline) {
 if ($logline['1'] == '') {
  echo '<tr>';
  echo '<td colspan="2"><b>' . date('D j M Y G:i:s T', $logline['2']) . '</b></td>';
  echo '<td class="c">' . $logline['5'] . '</td>';
  echo '</tr>';
  echo '<tr>';
  echo '<td class="a"><b>IP Address</b><br />' . $logline['0'] . '</td>';
  echo '<td class="b"><b>Hostname</b><br />' . $logline['4'] . '</td>';
  echo '<td class="c"><b>Browser/OS</b><br />' . $logline['3'] . '</td>';
  echo '</tr>';
 } else {
  echo '<tr>';
  echo '<td class="a"><a href="' . htmlspecialchars(urldecode($logline['1'])) . '"><b>Referer</b></a>';
  echo '<td class="b"><b>' . date('D j M Y G:i:s T', $logline['2']) . '</b></td>';
  echo '<td class="c">' . $logline['5'] . '</td>';
  echo '</tr>';
  echo '<tr>';
  echo '<td class="a"><b>IP Address</b><br />' . $logline['0'] . '</td>';
  echo '<td class="b"><b>Hostname</b><br />' . $logline['4'] . '</td>';
  echo '<td class="c"><b>Browser/OS</b><br />' . $logline['3'] . '</td>';
  echo '</tr>';
 }
}
echo '</table></div>';
?>

appreciate if someone could help, thanks.

Is there any other bits of code, nothing seems to be being written to the file...

oops, my mistake. i think last time i was too sleepy and tired... after looking at the code for few hours

the one above is to list the output from the log. below is the one which will capturing the users information

PHP Code:

<?php
// Getting the information
$ipaddress = $_SERVER['REMOTE_ADDR'];
$page = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
$referrer = $_SERVER['HTTP_REFERER'];
$datetime = date('D, M j, Y (T) \a\t h:i:s A');
$useragent = $_SERVER['HTTP_USER_AGENT'];
$remotehost = @getHostByAddr($ipaddress);

// Create log line
$logline = $ipaddress . '|' . $referrer . '|' . $datetime . '|' . $useragent . '|' . $remotehost . '|' . $page . "\n";

// Write to log file:
$logfile = 'log.db';

if (!$handle = fopen($logfile, 'r+')) {
    die("Failed to open log file");
}

file_put_contents($logfile, $logline . file_get_contents($logfile));

fclose($handle);

?>

this is the perl script, it has something like the time comparison, which i'm not sure in php, i'm still a newbie

if (-e "$hostfile")
    {
        open(HOST,"$hostfile");
        $hostline = <HOST>;
        chop($hostline) if $hostline =~ /\n$/;
        close(HOST);
        ($old_time,$old_number,$old_page,$old_browser) = split(/\|/,$hostline);
    }

    # save host and time info and check if this is a page reload
    open(HOST,">$hostfile");
    $seconds = time;
    print HOST "$seconds\|$ENV{REMOTE_ADDR}\|$ENV{'DOCUMENT_URI'}\|$ENV{'HTTP_USER_AGENT'}";
    close(HOST);

    if ($time - $old_time < $interval && $ENV{REMOTE_ADDR} eq $old_number && $ENV{'DOCUMENT_URI'} eq $old_page && $ENV{'HTTP_USER_AGENT'} eq $old_browser)
    {
don't do anything
    } else {
process it
}

anyway to convert this to php so that i can incorporate it into the above-mentioned code?

thanks.

hi,

i'm wondering, since php has more functionality, is session going to help?

i found this session code, but not sure about the meaning...

session_start();

$pageRefreshed = false;
if (isset($_SESSION['LAST_REQUEST']) && $_SERVER['REQUEST_URI'] === $_SESSION['LAST_REQUEST']['REQUEST_URI']) {
if (isset($_SERVER['HTTP_REFERER'])) {
// check if the last request’s referrer is the same as the current
$pageRefreshed = $_SERVER['HTTP_REFERER'] === $_SESSION['LAST_REQUEST']['HTTP_REFERER'];
} else {
// check if the last request didn’t have a referrer either
$pageRefreshed = $_SERVER['HTTP_REFERER'] === null;
}
}
// set current request as “last request”
$_SERVER['LAST_REQUEST'] = array(
'REQUEST_URI' => $_SERVER['REQEUST_URI'],
'HTTP_REFERER' => isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : null
);

appreciate your feedback
