What's wrong with phpdoc?

Question

phpstorm

Good afternoon, there is an array of $bookList and objects in it $book, when I designate them as @ var in phpDoc, phpStorm does not swear, but when I designate them as @ array and @ ojbect, wargning is displayed accordingly. What's the matter ?

Answer 1

@var array booklist
or
@var object[] booklist

Answer 2

@ array and @ ojbect respectively highlight the wargning. What's the matter ?

Is it because phpdoc does not have such tags, for example?
Where did you find @object or @arraysomething? docs.phpdoc.org/references/phpdoc/index.html
