<?php

$array = [0 => "foo", 1 => "bar", 2 => ["baz"]];

$associative = false;

var_dump(
    json_decode(
        json_encode($array),
        $associative
    )
);

?>

The above will output
<?php
/*
array (size=3)
  0 => string 'foo' (length=3)
  1 => string 'bar' (length=3)
  2 =>
    array (size=1)
      0 => string 'baz' (length=3)
*/
?>

Considering <?php $associative = false; ?> one might expect
<?php
/*
object(stdClass)
  public '0' => string 'foo' (length=3)
  public '1' => string 'bar' (length=3)
  public '2' =>
    object(stdClass)
      public '0' => string 'baz' (length=3)
*/
?>

an stdClass object instead of an array, but this is incorrect.
json_decode will always return an array for a sequentially encoded array, regardless of the ?bool $associative 2nd argument

Which is inline with the above mentioned docs/spec
    > Returns the value encoded in json in appropriate PHP type

Considering that the 1st arg was a sequentially encoded array as a json string
    '["foo","bar",["baz"]]'
