I had a question-suggestion based around the cool new operator we’re getting in PHP7, the ?? operator, which as I understand it is the functional equivalent to perl’s // operator; in that they both test for whether or not a variable is defined, rather than it’s truthiness.
This is not strictly correct. Though something of a misnomer, the 'null coalesce operator' checks if a variable doesn't exist, but also that it is not null, i.e. it functions like isset().
