Seperation of code and presentation is just as clean as in perl, I'm really not sure why people bring that up as a point for PHP... Templates slow things down, and I think Perl actually has the advantage when using templates (because of it's innate ability for text manipulation and regex). PHP can generate PDF, I'm pretty sure it can do WML, as well as some other page types. It also has the ability for graphics manipulation...
Language localization?
