What should the PHP host support?
The PHP host should support PCRE (Perl Compatible Regular Expressions) as the plug-in uses them to match and replace the tags from your post with the properly formated flash objects. PHP v4 is enough, thus you won’t need a PHP v5 host. The plug-in works on Windows hosts as well as on *nix hosts. The only cross-platform issue was the path detection for the embedded FLV media player which was fixed by v0.2.4.2.
