Typed properties problems View as Markdown

Where can I see progress of this work?

Hi Bob,

I've found a number of problems:

$ sapi/cli/php -r 'class Foo {public bool $b = false;} $x = new Foo;
$x->b->ops += 5; echo gettype($x->b),"\n";'

object

$ sapi/cli/php -r 'class Foo {public bool $b = false;} $x = new Foo;
$x->b->ops++; echo gettype($x->b),"\n";'
object

$ sapi/cli/php -r 'class Foo {public bool $b = false;} $x = new Foo;
$x->b->ops = 5; echo gettype($x->b),"\n";'
object

$ sapi/cli/php -r 'class Foo {public bool $b = false;} $x = new Foo;
$x->b[] = 5; echo gettype($x->b),"\n";'
array

Thanks. Dmitry.

On regular PHP 7, the array weirdness (Dmitry's last example) doesn't even
produce a warning:

class Shit {
public $yo = false;
}

$shit = new Shit();

$shit->yo[] = "what"; // quitly turns $yo into an array!

echo gettype($shit->yo); // array

That's pretty messed-up right there. At least in the object cases there's
an E_WARNING "Creating default object from empty value" - with the array
case, nothing, it just converts your boolean into an array. Yiiiiikes.
