Server problem or code problem???

Running IIS 5.0 on Server 2000

The default page served is HOME.PHP which utilizes several include files for various elements of the page. The Site Navigation table, Featured Link table, Google Search table, User Info table, Registration Info table and Link To Geek Emporium tables are all PHP includes.

The User Info table is the one most recently added (a couple of days ago) and it's been working fine as far as it goes. This morning, that table doesn't process nor does anything that comes after it on the page WHILE IT'S SERVED AS THE DEFAULT DOCUMENT. If you do a direct call to the doc (URL includes document name) it all processes correctly.

Like I said, this has been working fine for a day or two then all of a sudden it stopped doing so. I've temporarily gotten past it by putting the default doc back to HOME.HTM which uses a redirect to HOME.PHP thus causing it to process correctly. ??? Any ideas anyone ???

Aw c'mon... Not even a semi-educated WAG? Leave it to me to find a situation completely unique.

Just in case it might provide a little inspiration, here is the code for userinfo.php

PHP Code:


		
			
<?php

if(isset($_SERVER['HTTP_REFERER']))

{

    $url = $_SERVER['HTTP_REFERER'];

    $title = fetchpagetitle($url);

}

else

{

    $title = 'N/A';

}



echo '<table width="98%" border="0" cellspacing="0" cellpadding="2" valign="top" align="center">';

echo ' <tr>';

echo '   <th nowrap bgcolor="#666666"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC">USER INFO</font></th>';

echo ' </tr>';

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>Referrer:</strong> ',$_SERVER['HTTP_REFERER'];

echo '</font></td></tr>';

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>Page title:</strong> ',$title;

echo '</font></td></tr>';

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>IP Address:</strong> ',$_SERVER['REMOTE_ADDR'];

echo '</font></td></tr>';

$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>Host Name:</strong> ',$hostname;

echo '</font></td></tr>';

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>Browser:</strong> ',$_SERVER["HTTP_USER_AGENT"];

echo '</font></td></tr>';

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>Query String:</strong> ',$_SERVER['QUERY_STRING'];

echo '</font></td></tr>';

echo ' <tr><td bgcolor="#333333"><font size="-1" face="Arial, Helvetica, sans-serif" color="#FFFFCC" link="#FFFFCC" vlink="#FFFFCC">';

echo '   <strong>Remote Port:</strong> ',$_SERVER["REMOTE_PORT"];

echo '</font></td></tr>';

echo '</font></td></tr>';

echo '</table>';

echo '<br />';

function fetchpagetitle($url) 

{

    $fp = fopen($url, 'r');

    while(!feof($fp)) {

        if(preg_match('/<title>([^<]*)</title>/i', fgets($fp, 1024), $matches)) {

            $title = $matches[1];

            break;

        }

    }

    fclose($fp);

    return $title;

}

?>

I have no idea about PHP on IIS, sorry.

Just as a followup... I had the server rebooted and the problem cleared up. We still have no idea as to the particular nature of the problem or why the server should gag on that particular code only when serving the document as default. Way too queer.

Chapter two of followup.... within 24 hrs of the reboot, the php code started falling down again. I don't know why IIS would serve it correctly sometimes and not others, but I finally pinned it down to a function in the code. Once I removed that function (gets page title of referring page) the code seems to work fine regardless.
