Description:
------------
Hello,

I've this one on reddit ( https://www.reddit.com/r/lolphp/comments/3hm7hh/conjure_arrays_from_nothing ).
I've verified this in PHP 7 RC 3 but according to the author of the reddit post and to testing website such as 3v4l.org, it is a valid issue from PHP 4.3 to PHP 7.0.0 RC 3.

So as a brief description, you set a variable to false, than you implicitly turn it into an array, no error is triggered.
But when you set it to true, and then change it into an array, a warning is raised.

Test script:
---------------
<?php
$foo = false;
$foo["bar"] = "baz";

// No warning

$foo = true;
$foo["bar"] = "baz";


// Warning: Cannot use a scalar value as an array

Expected result:
----------------
Consistant output. Always or never. IMHO it should be always.
