Assigning values ​​to arrays. How?

Question

PHP

Interested in this question

function func() {
  $error = Array();
  return $error[] = 'Текст';
}
$a = fucn();

In this case, after returning the variable $a is assigned a string value.
In case you change

$error = Array();
$error[] = 'Текст';
return $error;

As expected, an array is obtained. Why is this happening??? Thank you.

Answer 1

In the second case, you return an array, and in the first case, the result of the variable assignment operation, and in php it will be the value itself, i.e. in this example a string.
