Other languages can fix that (they haven't yet) but at the same time PHP is fixing it's problems at a rapid pace. It seems that PHP is making more progress fixing it's problems and including modern features than other languages are improving their deployment situation.
One advantage of PHP, in my opinion, is that it supports multiple levels of commitment. I recently created a static website for my business; I didn't want the hassle of using a CMS or Wordpress. But I used PHP to include the common headers and footers and handle my contact form. In any other web platform (including PHP with a framework) is terrible overkill for a job like that. But if I want to do something more significant in the future, I can.
PHP's work cycle is also great; if done right you should have no build step. Just edit and hit refresh. I'm currently doing ASP.NET and it's just not possible to iterate as fast during development.
But honestly, I've used a lot of different platforms and PHP just isn't that different. Why choose PHP over all your other options? If your goal is distribution of your app then you can't go wrong with PHP because it's installed everywhere. And, depending on your language experience, you might be more comfortable in PHP because it's very literal; there's no monkey patching or heavy use of dynamic features. But really, there's no reason not use Ruby or Python over PHP.
