how to modify this code to include logging of ip address to another file

Question

please look at the simple php webpage code below

how can modify my code so that a log file is created on my server which logs each visitor's ip and whether it was successfully redirected to the correct page . something like that.

   <?php

$a = $_SERVER['REMOTE_ADDR'];
if ( $a == "117.96.112.122" )
{
        header("Location: ad_sams_mobile.html");
        return true;
}
else
{
        header("Location: ad_other_mobile.html");
        return true;
}

?>

Answer 1

See the PHP function file_put_contents. You'll need to use the append flag:

file_put_contents("log.txt", "IP: ". $a .", Location: ad_other_mobile.html", FILE_APPEND);

Answer 2

The Apache access.log should have all the information you need.

All you have to do is parse it.

Answer 3

Something like this:

$logfile = 'redirect.log';
$handle = @fopen($logfile, "a");

$a = $_SERVER['REMOTE_ADDR'];

if ( $a == "117.96.112.122" )
{
    $redirect_loc = 'ad_sams_mobile.html';
    header("Location: {$redirect_loc}");
 }
else
{
    $redirect_loc = 'ad_other_mobile.html';
    header("Location: {$redirect_loc}");
}

if ($handle && is_writable($logfile))
{
    $log = "{$a} -> {$redirect_loc}\n";
    fwrite($handle, $log);
    fclose($handle);
}
return true; // you always return true so just put it at the end

Answer 4

Or this for IP logging:

<?php
$file = fopen("log.html", "a");

$time = date("H:i dS F");
fwrite($file, "<b>Time:</b> $time<br/>" );

if( $REMOTE_ADDR != null)
{
fwrite($file,"<b>IP address:</b> $REMOTE_ADDR<br/>");
}

if( $HTTP_REFERER != null)
{
fwrite($file,"<b>Referer:</b> $HTTP_REFERER<br/>");
}

fwrite($file,"<b>Browser:</b> $HTTP_USER_AGENT<hr/>");

fclose($file)

?>
