This is a really great effort, but I noticed a handful of areas where the PHP example was off. I wonder if people with more experience with the other languages noticed the same thing for their language. Some examples: Null test: $var === null // omitted isset($var) // actually checks if $var exists and is not null (apparently-- I actually didn't know about the not null part) Undefined variable access: it's a notice. Many people consider it best practice in PHP to treat notices as error, because things like this are notices. Add time duration strtotime('+10 minutes') is more typical than the objects Array out of bounds behavior again issues a notice.
