I don’t quite understand the $query variable of “automatic global instantiation” in closure queries.

Question

Why not use dependency injection in closures? For example,

function(\think\db\Query $q) {

$q->where('sex', 0)->where('salary', '> ', '8000');

}

tp5.1, I can execute it successfully like this.

Answer 1

This is an anonymous function, not a closure
