Answer 1

In the second case, you return in the callback not the prev array, but or AND in the second iteration you get an error in an attempt to change the property '1' in the line, which, in fact, is written in the error text:tec.join(" ")tec

TypeError: Cannot assign to read only property '1' of string 'bla bla-bla'

Answer 2

Symfony 4.4 will add the ability to store keys securely, more details in the announcement .
