Using Perl code from PHP: php_perl extention, php_perl.dll

In my current project, it has some old code in Perl and new code in both Perl and PHP. the PHP and Perl code need connect each other, especially the session variables. currently, we need PHP to get Perl session variables.

Searching on Google, finally I get something useful
Http://devzone.zend.com/node/view/id/1712

Since I didn't find the compiled DLL at the beginning, I tried to compile from the source code (in order to do compilation, I also was forced to install MS Visual Studio, but still failed to build it .) maybe it's because my PHP is 5.2.0.

Fortunately, we found a compiled php_perl.dll which works for PHP 5.1.6 on my colleagues' computer. But the problem is our customer has a Linux server, need further tests later.
