As mentioned before if you want a quick way to some minor things with you site like displaying a simple visitor counter, PHP was made for it. But quick also often means dirty. There are frameworks now that will counter the dirtiness though.

As for what is actually "cool" about PHP, I would say nothing, however, I have to admit it is easy to find people willing to work with PHP. So PHP is maybe "cool" like 'Friday' was cool with so many people, I don't know, never been part of the "cool" crowd.
