I've this one on reddit ( ).
I've verified this in PHP 7 RC 3 but according to the author of the reddit post and to testing website such as, 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:
$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.

That needs a RFC (I guess… or at least some thorough internals discussion).

Suspending as it'll target minimum 7.1.
