PHP file download counter

I use htaccess to protect directory and granting access to download
file only for the authorized users. Just want implement simple PHP file
download counter for single file. I need track the number of downloads
of this file on my website, IP address and date. Since I have no access
to Apache log files, I need some other way, use script that will write
a log file. Is there some handy way?

Write a script that supplies the file download with the correct mime type
and in that script record the details you want to the place you want...

How to interface this with htaccess? I am new in Php, perhaps there is
ready scripts written for this tasks?

Johnny is right. Here's some code I've used before that does something
similar. This will log the request to a flat file then redirect the
user:

<?

//
// Class SimpleRedirectLog
//
// Create a simple redirect log. Sample usage:
//
// SimpleRedirectLog::logRedirect('file.zip');
//
// That will update a file called "logs/file.zip-access-log.csv"
// with the IP address of the client and the number of times the
// URL has been accessed. The client will be redirected to "file.zip".
//

class SimpleRedirectLog
{
function logRedirect($url, $logPath = null)
{
if (SimpleRedirectLog::logAccess($url, $logPath) !== false) {
header("Location: $url");
return true;
}
return false;
}

function logAccess($url, $logPath = null)
{
$ok = false;
$counter = 0;

if (is_null($logPath)) {
$logPath = dirname(__FILE__) . '/logs/' .
preg_replace('#[/\\\]#', '_', $url) .
'-access-log.csv';
}

if (!($fh = fopen($logPath, 'a+'))) {
trigger_error('Failed to open log file.');
} elseif (!flock($fh, LOCK_EX)) {
trigger_error('Failed to lock log file.');
} elseif (($size = filesize($logPath)) === false) {
trigger_error('Failed to get log file size.');
} else {
$err = false;
if ($size > 0) {
// Get the current counter value
$val = '';
$offset = -1;
for (;;) {
if (fseek($fh, $offset--, SEEK_END) !== 0) {
trigger_error("Failed to retrieve counter.");
$err = true;
} elseif (($c = fgetc($fh)) === false) {
break;
} elseif ($c == ',') {
if (!preg_match('/^[1-9][0-9]*$/', $val)) {
trigger_error("Stored counter is invalid: \"$val\".");
$err = true;
} else {
$counter = intval($val);
}
break;
} elseif ($c != "\r" && $c != "\n") {
$val = $c . $val;
}
}
if (fseek($fh, 0, SEEK_END) !== 0) {
trigger_error("Failed to seek in log file.");
$err = true;
}
}
if (!$err) {
$entry =
SimpleRedirectLog::csvEncode(date('Y/m/d G:i:s')) . ',' .
SimpleRedirectLog::csvEncode($url) . ',' .
SimpleRedirectLog::csvEncode($_SERVER['REMOTE_ADDR']) . ',' .
($counter + 1) . "\n";
if (!fwrite($fh, $entry)) {
trigger_error('Failed to write log data.');
} else {
$ok = true;
}
}
}

if ($fh && !fclose($fh)) {
trigger_error('Failed to close log file.');
$ok = false;
}

return $ok ? $counter : false;
}

function csvEncode($str)
{
if (preg_match("/[,\"\r\n]/", $str)) {
$str = '"' . preg_replace('/([" \\\\])/', '\\\\\1', $str) . '"';
}
return $str;
}
}

?>

You could modify this to use readfile() if you want to send the file
directly from PHP instead of using a redirect.

I tried script, but not work for me. What variables need be edited?

M.

Hi,

Try setting error_reporting(E_ALL) and watch for any errors. Pls paste
your script that uses the class...

By default you'll need a web-writable directory called "logs" located
in the same directory where the class file is.

Hi,

I tried link file to download:

http://www.mydomain.com/SimpleRedire...p?title=MyFile

M.

Hi,

You can add this to the bottom of the script to handle that
URL:

if (isset($_GET['title'])) {
SimpleRedirectLog::logRedirect($_GET['title']);
}
