QDBM on Windows

I'm running Win XP Pro/SP3, Apache 2.2.11 and PHP 5.2.9.1. I have a database built by a Perl program using its "dbm" database system that binds a file to an associative array. I have discovered via Google etc. that there's a PHP extension that can read/write this type of database. It is called "qdbm". I have followed the instructions in the PHP manual at http://uk3.php.net/manual/en/dba.requirements.php and related pages but nothing works. When I try to run Example 1 at http://uk3.php.net/manual/en/function.dba-handlers.php which calls dba_handlers I get an "undefined function" error. I have found the Windows binaries qdbm-1.8.75-win32.zip on SourceForge by following the instructions at http://uk.php.net/manual/en/dba.installation.php which say "Note: This was added in PHP 5.0.0. The qdbm library can be loaded from » http://qdbm.sourceforge.net. " but this .zip has many files which I don't know what to do with. Can someone please help? Step by step please. I've used Perl a lot but am completely new to PHP. -- Harold Fuchs London, England Please do *not* reply to my personal e-mail address.
