Question : error when calling php/xml file in browser

Hi,
I'm going through the following tutorial
http://code.google.com/apis/maps/articles/phpsqlflex.html#outputxml

I've created the php file in the snippet below and checked that my webserver supports PHP dom_xml functionality.

However when i call the file from a browser i get the following error;

Fatal error: Call to undefined function domxml_new_doc() in /home/b51272/public_html/v3/phpsqlajax_genxml.php on line 6

any ideas? thanks

<?php

// Iterate through the rows, adding XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  $node = $doc->create_element("marker");
  $newnode = $parnode->append_child($node);

  $newnode->set_attribute("mobNumber", $row['mobNumber']);
  $newnode->set_attribute("user_type", $row['user_type']);

Answer : error when calling php/xml file in browser

I think you should add an external redirection web site rule to the site document for mail.mydomain.com, with as follows:
incoming url pattern: *
Redirect to this URL: https://www.otherdomain.com/Folder/file

Starting the redirect URL with a protocol specifier makes it an external redirect which send back the new URL to the browser (as described in the Administrator Help).

If you had read the Administrator Help (Topic: Web Servers:The Domino Web Server:Hosting Web sites:Web Site rules and global Web settings), you would have seen that putting in mail.mydomain.com in the incoming pattern is not how you should specify the rule.

if entering https://www.otherdomain.com/Folder/file does not work, while there is actually such a file on the specified path, then look for a conflicting Web rule defined for otherdomain.com
Another possibility is Domino is running on a case sensitive OS or file system.
