I don't disagree that there are times when PHP might be the right tool, but these reasons are pretty bad.
PHP's support for "lambda" is a joke, even compared to Python's limited lambdas. I question how often "eval" is used in practice, except maybe to get around limitations of the language.
In fact, there is nothing on that list that Python and Ruby can't do, except for a few things that are probably bad ideas anyway. If the author is impressed by built-in functionality like array sorting, I am guessing they have never seen the standard libraries of Python or Ruby.
