Sanity Check

I just want to make sure I'm not losing my mind.

I placed the following in the footer of my php link directory:

<table width="100%" border="0" cellspacing="0" cellpadding="1">
<tr>
<td height="1" align="center" bgcolor="#ffffff"></td>
</tr>
</table>
<?php
ini_set ("include_path", ini_get ("include_path") . ':../:../../:../../../:../../../../');
include ('ad_network.php');
echo $ad_network[0];
?>



I placed this in my ad_network.php file in the root of my site:

<?php
if (!function_exists('file_get_contents')) {
function file_get_contents($url) {
$handle = fopen($url, 'r');
$string = fread($handle, 4096000);
fclose($handle);
return $string;
}
}

if (!function_exists('make_seed')) {
function make_seed() {
list($usec, $sec) = explode(' ', microtime());
return (float) $sec + ((float) $usec * 100000);
}
srand (make_seed());
}

if (!isset($_SERVER)) $_SERVER = $HTTP_SERVER_VARS;

$ad_file = 'ad_network_ads.txt';
for ($i = 0; $i <= 11; $i++) {
$p = substr ('../../../../../../../../../../', 0, $i * 3);
if (file_exists ($p . $ad_file)) {
$ad_file = $p . $ad_file;
break;
}
}

if (is_writable ($ad_file)) {
$ads = file_get_contents ($ad_file);
$ads = explode ('<ad_break>', $ads);

if (count ($ads) < 401 || $ads[0] + 900 < time()) {
$new_ad = file_get_contents ('http://ads.digitalpoint.com/network.php?s=' . $_SERVER['SERVER_NAME'] . '&type=link');
$ads[] = $new_ad;
$ads[0] = time();
if (count ($ads) > 401) unset ($ads[1]);
if ($new_ad) {
$file = fopen($ad_file, 'r+');
if (flock ($file, LOCK_EX)) {
fwrite ($file, implode ('<ad_break>', $ads));
ftruncate ($file, ftell($file));
flock ($file, LOCK_UN);
}
fclose ($file);
}
$ad = end ($ads);
} else {
$ad = $ads[rand(1,count($ads) - 1)];
}
$ad_network[] = $ad;
while (count ($ad_network) < 5) {
$ad_network[] = $ads[rand(1,count($ads) - 1)];
}
} else {
$ad_network[] = 'You must set the "ad_network_ads.txt" file to be writable.';
}
if (substr (@$_SERVER['DOCUMENT_NAME'], -6) == '.shtml') {
ini_set ('zlib.output_compression', 0);
echo end ($ad_network);
}

?>


I created a file called ad_network_ads.txt and placed it in the root.

Now when you go to: http://www.playgroundmall.com/resources/addlink.php you should be able to see the ad running in the footer. I'm not seeing anything running there. Have I lost my mind?
