To entire namespace just like:
<?php declare(strict_types=0);
namespace_declare('Acme\Animal', [
'strict_types' => 1,
'dynamic_object_properties' => 0,
...
]);
namespace Acme\Animal declare(
strict_types=1,
dynamic_object_properties=0
); // <-- this works same as namespace_declare call above
namespace Acme\Machines {
// here we have strict_types=0 turned off
}
