Not sure what conclusion the article reaches although the author appears not to like PHP.
I prefer Perl, not because I can prove that it is superior to PHP but just that I am familiar with it and it does most of the things I need to do. My only experience of PHP is the GD function for manipulating images, which I regularly use. The best part about Perl, by far, are the people who frequent the Perl Forum, they are knowledgable, helpful and do not treat newbies as second class citizens.
Just my biased opinion.
