PHP and Perl are basically like Spanish and Italian when it comes to syntax. Both can more or less interoperate with the assistance of lots of hand gestures and facial expressions.
Same here, because I knew they intersected and presumed it was a trick question. Technically, I believe it is neither valid perl nor PHP because it's missing an opening brace on one of the if statements.
PHP lets you skip using curly braces for conditionals. I've seen real-world code which used this style only once, and it was about as bad as you'd expect.
Yeah, I suspected that, but it looked like there was a close brace and no open brace. (I only noticed because I was specifically looking at the braces to try to determine if it was PHP.)
