So...do any of the PHP bashers do any actual extensive coding in PHP? Have you ever looked at the code in Drupal 7/8?
Seriously, I am always baffled by everyone who starts ranting on how crappy PHP is. I have done mostly PHP development for 12+ years. I have yet to have a site hacked, or SQL injection exploited. It is a very solid language, it can be made VERY fast (JIT is also coming down the pipe out of the box in 6+). It lends itself to rapid prototyping and easy patching / testing. There is a module / plugin / snippet of code out there for pretty much everything. It will run on a windows server, a debian box, and CentOS pretty much the same.
Loose variable typing is not always bad thing, and you can always cast variables anyway:
$_GET['my_var'] = (int) $_GET['my_var'];
Ta-da! We definitely have an integer now!
I have written entire chat bots with raw socket connections in PHP...it can pretty much do everything...and do it quickly.
