PHP Show Users on this Page - PHP

Is there any PHP code that shows the amount of users that visited a certain page in the last 15minutes?

Thanks

for this forum, specific php file, or arbitrary page? bit confused.

Just a specific page, not to do with this forum

i'll test properly tomorrow, but here is an example with no error checking. not completely optimal, it rewrites the file per load.. couldn't think of a better solution this late. fyi- it's unique to ip addresses.


&lt;?
$ip = getenv(\"REMOTE_ADDR\");
$user_db_fname = \"_visited\"; // filename
$timeout = 15; // minutes

if (!file_exists($user_db_fname))
{
    $out_file = fopen($user_db_fname, \"a+\");
    fclose($out_file);
}

$file = file($user_db_fname);
$parsed_file = array();
foreach ($file as $val)
{
    $val_arr = explode(\";\", $val);
    $parsed_file&#91;$val_arr&#91;0&#93;&#93; = (int)$val_arr&#91;1&#93;;
}

$cur_time = time();
$parsed_file&#91;$ip&#93; = $cur_time;
$out_file = fopen($user_db_fname, \"w\");
foreach ($parsed_file as $key =&gt; $val) // ip =&gt; time
{
    if (($cur_time - $val) &gt; $timeout * 60)
    {
        unset($parsed_file&#91;$key&#93;); // timed out
    }
    else
    {
        fwrite($out_file, $key &#46; \";\" &#46; $cur_time &#46; \"\r\n\");
    }
}
fclose($out_file);

echo sizeof($parsed_file) &#46; \" users visited in the last \" &#46; $timeout &#46; \" minutes&#46;\";
?&gt;

Howdy, Stranger!
