I want to put my Weblog on a ISP Server but they don't support CGI . So is there any chance that i can convert / or download Movable type 2.63 in PHP?

Movable Type is written in Perl and there is not a PHP version offered (and I doubt there ever will be).  If you are limited to PHP, you should research some of the other blogging software available, some of which are written in PHP.

Here's a good start.

Thanx. I will check it out..
