It may be the way your server handles PHP virtual().
virtual() is an Apache-specific function which is equivalent to <!--#include virtual...--> in mod_include.
This function works only when PHP is compiled as an Apache module, since it uses the Apache API for doing sub requests.
You may want to try this:
Comment out line 47 by adding 2 forward slashes in front of it ( i.e.... // ).
Then on the next line down add this:
echo $listing_num[0];
You should see a different listing number each time you reload the page.
If this works ok, then can build the whole thing right in this script. Here's an example of the whole script:
<?php
//Path to listing.dat.cgi file.
$path = "cgi-bin/listman/data/listing.dat.cgi"; //Put listings into an array.
$array = file($path);
//Remove first 3 lines of listing.dat file.
array_splice($array,0,3);
//Randomize the array.
$element = $array[rand(0, count($array)-1)];
//Separate each field.
$listing_num = explode("¡", $element);
//Strip everything past the 75th field.
array_splice($listing_num, 75);
//If no image, let's use a default one.
if ($listing_num[4] == ''){
$listing_num[4] = ('nophoto.jpg');
} else {
$listing_num[4] = $listing_num[4];
}
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Random Listing</title>
</head>
<body>
<table border="0" cellpadding="0" style="border-collapse: collapse" width="150" id="table1" bgcolor="#000080">

<table border="1" width="150" bordercolor="#003366" bgcolor="#DFDFDF">

<p align="center"><br><a href="http://yourdomain.com/cgi-bin/listman/exec/search.cgi?view=<?php echo $listing_num[0];?>"><img src="http://yourdomain.com/listman/listings/images/<?php echo $listing_num[4];?>" border="0" width="140"></a></p>
<font face="Trebuchet MS" size="2" color="#800000"> <?php echo $listing_num[14];?><br>
<?php echo $listing_num[16]." ".$listing_num[17];?><br>
<?php echo $listing_num[19];?><br>
<a href="http://yourdomain.com/cgi-bin/listman/exec/search.cgi?view=<?php echo $listing_num[0];?>">details...</a><br></font>
</td>
</tr>
</table>
<table border="1" cellpadding="0" style="border-collapse: collapse" width="150" id="table3" bgcolor="#000080">

<br>

</html>
Now you'll see from above I looked in my listing.dat.cgi file and examined each field to see what it represents.
Starting with the first field $listing_num[0] is my listing number, followed by the separator "¡", then my second
field would be $listing_num[1], 3rd field would be $listing_num[2], and so on...
Also I have an if,else statement in this script that says if no image is found, use an image which i created and
uploaded to my \listman\listings\images folder. It's a jpg image that says "No photo available".
You can insert each field you want to display using this:
<?php echo $listing_num[x];?>
"x" represents the field position of the item to display.
After your done, make sure this file's name ends with the .php extention.
Then you can use a include statement in your .shtml page to include this php page.
Example:
<!--#include file="random.php" -->
Hope this helps everyone who wants a random listing to display perhaps on their home page.
