I'm sure you can do the same thing in Perl, it's just a matter of figuring out how.
You can do pretty much the same things in Perl and PHP. It's just a matter of what language you will learn faster so that you can get to work faster. If you already know some perl, then it might be faster to keep learning that and gear your learning towards web scripting... If you want to tackle a new language, then PHP is fairly easy to learn.
Either way, you can do you job in either language...
