It's a PHP 7 feature, it's called "return type declaration": basically you declare that the function will always return something having the declared type; if you return something else, like an integer, or don't return anything, a TypeError is thrown. I really like this feature, strict type force you to write better code.

This is great, guess most of the time I use PHP in a too "simple" way and should get more familiar with such details as it really helps to improve and ease the code :)

It's basically like in C++, or similar languages, when you define a function with a specific return type like

static QualityIssue fromArray(vector<type> &source){}

Thanks for the explanation, I struggled to find a good search query for this question with only the code.
